Some people are just angry and will direct it at whatever. Not saying it's OK, but once you really internalize the idea that people's reactions say more about themselves than about you life gets better.
That makes the bold assumption those people aren't your boss or your customers or your landlord or the policeman stopping you on the side of the road. There's real risk, both financially and physically, to just assuming that "random anger" is something you can internalize and ignore.
People who are "just angry and will direct it at whatever" can be very dangerous, as we've seen in the US even this week and in every school shooting and terrorist attack for years.
This is, terribly, the American experience. It used to be the Irish and the Italians before we decided they were "White enough." It doesn't mean we should just ignore it and accept it. If you're mad, that doesn't give you a pass to be a racist asshole to the first person less pale than a porcelain plate you see.
If anything, the fact that people have to know and cope with random Americans being this exact sort of racist asshole to them is the reason they form their own communities and see themselves as Black Americans or Asian Americans or any other sort of national or racial group.
