> Speech that singles other people or groups out for different treatment or is otherwise racist, sexist, etc is intolerant.
I think most people can get on board with that. The trouble comes when people start berating others for using words/phrases like blacklist, sanity check, backlog grooming, master, and spaz - just to name a few. 99.9% of people who use these words do not possess the mens rea of bigotry or intolerance.
E.g.: Right now, someone who read your comment is probably enraged on behalf of the people who have been hit by buses. Most of us know you mean no harm by it.
