Not everyone thinks this, but I know an extreme right-winger who thinks this. He is also a conspiracy theorist who thinks non-white people are out to get white people so, yeah, odd.
Not every immigrant is illegal or bad. I know a girl who didn’t speak English for 3 years when her family legally immigrated, so of course she’s been told this.
Oh if you aren’t brown you’re ok. White places like Germany are the immigrants that are ok. Haven’t you heard “If it’s brown flush it down. If it’s yellow let it mellow.”? A lot of people think that refers to bathroom business but really it’s gop immigration policy.
