All of this, but if you'll all indulge me, I just want to spell it out again a bit differently, because I think it's important: once you start thinking of "good" and "bad" as teams you belong to, not only do you become blind to the evil you perpetuate, but you start thinking of evil as good. Using the example above, is racism bad? Most people, I hope, would say yes. But when you think of good and bad as teams you're assigned to, rather than things anyone can do, it doesn't matter whether racism is good or bad, it only matters which team is doing it. If you're on the "good" team, then you can be as racist as you like, as long as you're being racist to the people on the "bad" team. Rather than racism being something that's always wrong, no matter what, now you've created a class of acceptable targets that you can get away with being racist to, because you're on the "good" team and they're not. This can happen with anything, not just racism. Fatphobia, homophobia, xenophobia, sexism, misogyny, transphobia, ableism...anything.
