It’s because being hateful has become part of the conservative identity. To be accepted as a right wing conservative you have to spew hateful garbage about something pretty much constantly. If you don’t then they think your weak, or start calling you a RINO

The right wing has a long history of real repression. Think slavery, segregation, Jim Crow (simply saying it doesn’t do it justice), voter suppression, KKK, mob violence, etc. As much as I hate to realize it, they were fundamentally built on violence and hate. It’s never left them. Especially the mentality, which is “my way or violence”.

This is also why they project the left is violent. Because they are, so they assume everyone else is too. So they try to portray left groups as violent. Same with having an agenda. They have one, so they assume everyone else has one too. It’s all projection.

Because liberals see “the world vs the ideal world” we see problems and we try to correct them.

Conservatives see “us vs them” and burning the world to the ground is fine as long as “The others” burn with it.

Disclaimer: I wondered the same, since 2014, and this is what I puzzled together for myself, read it with that in mind!

I believe a lot of it can be traced back to the wealthy and to conservative think tanks / media control by right wing moguls.

Back in the 1960s and 1970s, conservatives were perceived as well-off business people trying to protect their own wealth (I’ve read that people used to say things like “I’m not rich enough to vote Republican” or children shouting “last one in the house is a dirty Republican”). You can even see old movies dunk on conservatives (i.e. take Stanley Kubrick’s “2010: The Year we Make Contact” (1984), at the beginning, with the satellite dish tower, the protagonist noses off about reactionaries being in control of congress, thus leading the country towards war).

This is the rather extreme election result from 1964:

Because liberals mostly were Democratic Party voters, Republicans and their wealthy donors tried to alter public perception of liberals (i.e. make it undesirable for their Republican indoctrinatees to be liberal). This included taking over the media (and Reagan conveniently cancelling the Fairness Doctrine in 1987, which gave political bias in the media some guard rails), then painting liberals as all things undesirable: arrogant, weak, clueless, leeches, etc.

Having a “hate object” worked so well that they kept capitalizing on it. Much of it was/is just slinging sh*t against the wall and looking what sticks, but think tanks are indeed looking at what sticks, so successful patterns get repeated. Some of these successful patterns I can see are: installing a victim complex in conservatives (feeling their back against the wall, they lash out easier, ensuring anyone talking about conservatives is conditioned to use very soft gloves) and the two-year bogeyman, often trying to capture, redefine and vilify some prior existing concept (thus, when the campaign hits, indoctrinatees can find lots of “proof” online of this thing existing).

For example, social justice used to be universally agreed on as a good thing, woke used to mean remaining aware of systemic inequalities, now they make conservatives pop an artery. This has been going for a while (the “hate object” over time has been rock music, hippies, metal music, supposed satan worshippers, pen and paper games, paganism+atheism, video games, social justice activists, cancel culture, black lives matter, critical race theory, wokeness, …)

And I think, yes, your perception is spot on. This is, for example, what I get when I search for “anti-conservative t-shirts” (if it’s too tiny, try it yourself - they’re all anti-liberal):

TL;DR: conservatives are intentionally made and kept angry. It keeps them unified against a bigger enemy (see Genghis Gambit), drives them to go vote and prevents voters from switching sides even if they do not like some things the conservatives are doing. Add to that Russia amplifying this division like there’s no tomorrow. They’re installing this hate for liberals both in tankies and in far-right bigots (and, as far as I can tell, anti-liberal sentiment is pushed into Russian society, too).

Well, well, well. Looks like we got ourselves a real thinker over here.

Let me grab my decoder ring and my degree in bullshit interpretation, ‘cause this shit needs unpackin’.

First off, ObliviousEnlightenment, huh? More like ObliviouslySpoutin’Nonsense.

Lemme tell ya, this whole liberal versus conservative hate thing is a load of horse shit.

Hate knows no political boundaries, kid.

It’s like ravioli—some folks love it, some folks hate it, but it don’t matter what side of the aisle you’re on, you still gotta respect the ravioli.

Now, as for this “us vs. them” mentality, that’s just human nature, plain and simple. We all got our gangs, our tribes, our little groups we run with.

But the problem ain’t the conservatives or the liberals, it’s the goddamn extremists on both sides stirrin’ the pot and throwin’ gasoline on the fire. They’re the ones spewing hate and takin’ things too damn far.

As for the whole muting and shamin’ thing, lemme break it down for ya: liberals tend to police their own when someone goes off the deep end, while the conservatives let their crazies run wild and pretend they don’t exist.

That’s why you see more visible hate from one side than the other. But make no mistake, there’s assholes on both teams. As for you feelin’ isolated, boohoo.

Welcome to the fuckin’ club. Life ain’t fair, and neither is politics. You wanna survive? Learn to navigate the crazy and find common ground.

Stop whinin’ and start thinkin’ for yourself. Don’t be another sheep bleatin’ out talking points.

That’s my two cents.

Now, if you’ll excuse me, I got a date with a meatball sub the size of my head.

They do hate them, but generally conservatives believe in personal failings so do direct action against individuals, liberals believe in systemic failings so direct their effort towards changing the system, not the individuals.

Because conservatism is no longer a set of political beliefs. In the modern conservative movement (basically starting in the 80s, liberals and conservatives were much different before that) conservatives had social beliefs, like preserving cultural norms, promoting religion, and maintaining the nuclear family, as well as fiscal beliefs, like limited government, individual liberty, fiscal responsibility, free markets, and a whole lot of other bullshit that basically boiled down to, “we don’t want to pay taxes.”

Now, conservatism is really only about establishing an in-group and othering their opponents. Oppositions to trans rights may seem like an attempt to preserve cultural norms, but it’s real goal is to create outrage and panic over trans, “groomers.” Objections go CRT and DEI serve a similar role in othering people of color. “Wokeness,” is just a meaningless catch-all for, “enemies.” Similarly, fiscal policy is meaningless, and can be picked up and discarded whenever convenient; corporations can be deregulated and given tax breaks in service of the free market, but subsidized or bailed out whenever needed.

This is because modern conservatism isn’t a political ideology, it’s a fascist movement. I mean that literally, and while the meaning fascism is notoriously hard to pin down, I use Umberto Eco’s 14 properties of fascism. And, to bring this back around to your original question, fascists hate liberals because hating a group is very important to a fascist movement. The modern conservative hate for liberals is especially clear in Eco’s 4th, 5th, and 7th properties of fascism (disagreement as treason, fear of differences, and obsession with plots, respectively).

So, tl;dr: the one-sided hate that conservatives have for liberals is because conservatism is no longer a coherent political ideology, it’s a fascist movement.

Many many liberals were raised by conservatives.

Many many conservatives raised eventual liberals and are aghast.

I don’t need to camp out and bully conservatives. I spent enough of my childhood immersed in their insanity. I’m just done.

You and I are on different parts of the internet it seems. As a non American, your guys’ politics frighten and confuse me. The amount of hatred seems pretty damn comparable on both sides. Also neither of your partied are actually very different. Just different flavours of authoritarian.

The parties differ not so much in their (propagated) goals, but in the methods they are prepared to use.

Gunna take this as Liberal/Conservative as party brand names rather than strict social ideology and you’re talking about “the left” more generally.

I think the short answer is empathy. When you dig down to the bottom a lot of the discussion on the left talks about different forms of human needs. A need to feel accepted and loved, desires to exist publicly without fear… It is a radical form of empathy that asks you to put yourself in multiple pairs of shoes and see the world through perspectives you aren’t naturally born into. The ultimate aim is to achieve a picture of humanity which is inclusive of the widest possible range of understanding.

In that way “Conservatives” are also people. It is not impossible to empathize with their issues. It takes a lot cognitively to internalize this new data and a lot of the rejection from the right comes not from outright cruelty but a desire for things to be and remain simple and easy. They don’t want to stretch themselves and are scared of a world where that is something they are forced to do. The issue is a lot of the people selling the pitchforks on that side are doing it because it benefits them. That desire to understand encompasses the motives of individual Conservatives and splits them apart. A lot of the issues Conservatives have is that the left is “preachy” that we act like we’re better than them and that does come from somewhere. Some leftists do just want to be the smartest most correct person in the room but others are just waiting for the Conservatives they know to be more understanding of other people who they learned about so they stop being mean. The person who pitties the school bully is often their target because that empathy seems to the bully like condescension.

This is the broadest stroke I can make of it:

Conservatives decisions are based on instincts and lower brain functions like fear and hatred.

Liberals decisions are based on marginal benefit and rational decision making based on a combination of large and small scale unbiased data and historical outcomes.

There are tons of outliers and vocal minorities that break the rule, but basically a conservative thinks a liberal should face eternal punishment, while a liberal thinks they’re not fit to judge a conservative.

Saw a cartoon years ago. Panel 1 = “How Democrats See The World.” It’s a globe with the USA divided into Red States and Blue States. The rest of the countries are pink/green/orange except for a few black spots with a skull and crossbones marked ‘Terrorists.’

Panel 2 = “How the GOP Sees the World…” Same globe, except there are only two colors; the Red States and everything else is “Terrorists.”

Not sure “liberals” is the right word, because it kind of encompasses all of the left, of which liberals are more center than left.

Anyway…

Because it’s at odds with with our moral compass and our knowledge of how human psychology works. We believe in people’s ability to learn, change, adapt, and become a better person. We see it practiced better in Europe than America, at least very often in respect to the criminal justice system, which the American version is abusive, unhelpful, and, well, conservative. On the other hand, the left thinks that even the conservatives that hate us deserve at least a bare opportunity at education and redemption. (Or at least most of the left anyway, tankies notwithstanding, of course.) We have science that supports compassion and conversion works better than abuse and ostracism. It takes a lot of fucking time and effort. A lot more than many would say they’re worth, and I get that, but it doesn’t mean it’s impossible.

We don’t hate them the same way because we’re not in a brainwashed cult like they are. While a lot of them may be too far gone, not all of them are, and as things spin out of control in the conservative world, increasing numbers of them are starting to question what they’re backing. It’s part of why the crowds protesting for Trump have slowly dwindled to pathetic numbers and have gotten increasingly strange and unhinged. Only the true believers are left, and their numbers are already dwindling in terms of those willing to come out and risk it for Trump.

Even when understanding the Paradox of Tolerance, you’d be hard pressed to find large numbers of leftists who think the best solution is the same kind of senseless eradication of the enemy that conservatives want. You’d find a large number of them who increasingly want to be armed and prepared if they are attacked by violent conservatives, but far fewer that want to be the one to fire the first shot in such a war.

Also, as to a counterpoint, I don’t know many leftists who don’t hate cops. Cops are pretty much universally conservative thugs and universally hated by everyone on the left.

Hate requires you to consider them first competent with shared common values that inform their beliefs and actions. Otherwise it’s mostly pity and disgust that they have no values other than authority and loyalty like a criminal enterprise, and usually can’t tell if they are being evil on purpose or by accident/inaction/ignorance.
