I actually don’t claim to be able to recognize that. The guy at the bar next to me ranting about how “Islamic immigrants had ruined Europe, it was all essentially uninhabitable for white people now” was OBVIOUSLY racist. Oh my god. And yes, I absolutely confronted this asshole about his fucked-up clearly wrong perspectives. This? Hell, even what happened at Starbucks with those two guys? It’s less clear to me. Very open to it, and very cognizant of more obvious racism. Also cognizant of how if most Starbucks most of the time don’t call out white people for hanging out but not buying anything, and then the time it happens that leads to an arrest, it’s black people, that’s absolutely a sign of societal racism playing out. But it still doesn’t mean specifically that the person who called the cops on those guys was a racist.
As I’ve said before — we live in a racist system, and as such, we all participate, at times, in that racist system. It’s not a good thing, we should work to change it.
And the reference to your career was because presumably, as a physicist, you’re quite used to working around a lot of fellow smart people. Some people are really fucking stupid. They’re more likely to have a job taking tickets, frankly, than probing the subatomic nature of physical reality.
