I think another recent piece in the Atlantic, http://www.theatlantic.com/magazine/archive/2015/09/the-coddling-of-the-american-mind/399356/ makes very good points about the dangers of giving too much power to language, and equally of being too scrupulous of protecting everybody from speech they find offensive. Today’s oppressed are tomorrow’s oppressors, a revolving door of changing mores. I would rather engage with than moralize and demonize those who use words I don’t like. The minute I label someone as sexist or racist or homophobic the conversation ends with my having taken the high ground and written them off. What if we just took a deep breath and asked “Huh, what’s that about? Tell me what you mean when you say that.” And then have a conversation.
Ok, perhaps not with Mr. Trump. But I’m sure I can find some other offender without too much trouble.
