According to your link, Ashkenazi Jews are descended mostly from Europeans on the maternal line but from Near-Eastern, “Semitic” people on the paternal line. The term “Semitic” comes from the biblical Shem, the son of Noah. So if Semitic ancestry were a real thing, then it would refer to the male line, and Ashkenazi Jews would have it.

Past research found that 50 percent to 80 percent of DNA from the Ashkenazi Y chromosome, which is used to trace the male lineage, originated in the Near East, Richards said. […] Richards and his colleagues analyzed mitochondrial DNA, which is contained in the cytoplasm of the egg and passed down only from the mother […] All told, more than 80 percent of the maternal lineages of Ashkenazi Jews could be traced to Europe, with only a few lineages originating in the Near East. […] “The simplest explanation was that it was mainly women who converted and they married with men who’d come from the Near East,” Richards told LiveScience.

But of course, Shem wasn’t a real person and there is no such thing as “Semitic” ancestry. The term antisemitic is a fossil left by 19th-century European racial pseudoscience weaponized against Jews living in European countries. There’s no reason to apply it to a different group of people unless you actually believe that certain races were descended from the biblical Shem.

The same is true of the Semitic language family. The Afro-Asiatic language family used to be called “Hamito-Semitic” from the belief that Africans descended from the biblical Ham and Asians from Shem. Linguists have updated that name, but for now no term has dislodged “Semitic” as the name of a language family.

If you want to claim that the term “antisemitic” refers to the Semitic language family, then it’s a prejudice that doesn’t exist. There’s no one on Earth who hates Arabs and Jews because they speak Semitic languages but is fine with Iranians and Turks. Hatred of both Arabs and Jews is almost always based on race, religion, and politics, not technical classifications of language families. Yes, Elon Musk called Arabic “the language of the enemy,” but there’s no doubt that he’d say the same thing about Farsi, or any other language spoken by non-white Muslims.

And finally, while Jews in the diaspora stopped speaking Hebrew and Aramaic as vernacular languages, they have always prayed in Hebrew and taken Hebrew religious names. European Jewish vernacular languages like Yiddish and Ladino carry Hebrew and Aramaic influences. And of course, many Jews historically spoke Judeo-Arabic, which is obviously a Semitic language.

Zionists and Elon Musk are racist, Islamophobic imperialists. There are plenty of terms to criticize them that aren’t confusing and pseudoscientific.

The best app is whatever you use to consume media in the target language.

The only way to acquire a language is to expose yourself to it in a natural context. You can’t acquire a language just by studying with flashcards or grammar exercises or whatever – any app that offers enhanced versions of those will at best be a minor supplement to actually using the language.

Most human males should be castrated.

Men commit almost all rape and murder, but no one seems to think this is a problem we need to do anything about. If any other group committed 90% of serious crimes – let’s say immigrants – people would be calling for them to be rounded up and exiled. But when it’s men, that’s just the way things are, nothing to be done about it.

But we know exactly what to do about it when we’re talking about other species. We castrate male cattle because bulls are dangerous and steer aren’t. Violent criminals typically have elevated testosterone levels. It doesn’t take a genius to realize that putting men on testosterone-blockers is going to make them less dangerous.

What will be the other effects?

1. Men will be be weaker—Meh, physical strength is less useful now than it was in the past.
2. They’ll have less hair on their bodies and more on their heads—Awesome.
3. They’ll won’t be able to get hard—That’s what viagra is for.
4. They’ll lose fertility—They can go off blockers while they’re trying to have a child. Or you could just have a small number of uncastrated sperm donors.

I’m an anarchist, so I don’t want to force this on anyone. But if I believed in prisons or police, I would also believe in mandatory castration.
