One of my coworkers commented on one of our difficult patients calling the weekend crew racist against them and how ridiculous it was because both the patient and the weekend nurses are black. I was like oh yeah no that’s because the weekend nurses aren’t black (being a cultural term for African-American), they’re African. Emphasis on the not-born-American. That’s different (to people who care about that sort of thing). Is it rational? Not even a little, but racism, despite the claims of phrenology et al, is about as far from rational as you can get.
