I was once among a group of (fellow) university-educated expats, during a stint living abroad in the 2000s. While we were socializing, somebody asked everyone to say what group of people they would make disappear. (I can’t remember if it was kill/erase/nuke/remove from a map that was said, but something along those lines.) People’s answers that day (and their insistence that I, too, should “jokingly” hate some group of people and want them to die) taught me a lot. On top of that, I also am part of one of the groups that was named (no, I am not mixed race-- it was just ignorance the guy’s part).
