Really? I'm not sure why you inferred "only" from that. Many immigrants (regardless of legal status) work many different jobs. Obviously. While not all immigrants pick fruit, pretty much all fruit picking jobs are filled by immigrants (for now). Many stories out there about farmers trying to hire non-immigrants without much luck. The "Take Our Jobs" campaign was very interesting. And worth looking up (in my opinion).
Please tell me that you aren't so sensitive that you missed the joke? The idea of someone that pale working outside, is funny. As is the idea of someone with that body doing manual labor. The same way that comedian Bill Burr working as a roofer, in the summer, as a redhead, is funny. Probably why it was part of one of his jokes. He's hilarious! I'd recommend his comedy to almost anyone. Of course, if you are sensitive, that's fine. You be you. But anyone who is easily triggered by comedy should stay away from Bill Burr's politically incorrect humor.
Being racist is judging, and assuming negative things about someone just by looking at them. It seems to me that you saying that I'm a racist, withOUT even looking at me is clearly you judging me, and assuming negative things about me. So what would we call that? It can't be racism, because I don't even know your race & you don't know mine.
Then again, I'm not judging major things about the character of strangers on the internet anyway. I like humor. I don't like things that Elon Musk does. So, I was making fun of him. And the anti-immigrants who clearly have no idea how much their grocery bills are going to go up if they get what they claim they want. And calling out anti-immigrant people who claim they aren't racist, but don't seem to have a problem with immigrants who can't get a tan.
