It is politics of The Other. To the conservatives, the ingroup is Americans and the outgroup is non-Americans. To the liberals, their ingroup is the conservatives' outgroups and their outgroup are the conservatives. This is why you will see things like libs cheerfully go into dangerous locales to prove everything is OK. These are their ingroups! And then they get beaten, stabbed or run over and can't understand what happened. To the people that live there, all Americans are definitely The Other to them, and thus are fair game.

I think everyone knows how The Other gets treated: you can do anything to them. They're not people, so they are outside the law. That's where the word "outlaw" came from, once you were declared an outlaw it was no longer a crime to do things like rob you or kill you. With all the things Trump can be criticized for (correctly), you see people calling him a piece of shit because he's fat. Or Clarence Thomas or Candace Owens being called a house Ns. I mean, that's the best you've got? You can't pick up any of the problems they are clearly guilty of? No, it has to be one of these.
