Bigotry is a political opinion, but the idea that all political opinions deserve identical respect is really dumb.
Some people’s ideas are bad, actually. It is fine and good to tell them where to shove it.
The kneejerk demand for “civility” confuses polite responses for appropriate responses. Some people are monsters. Some people need to hear, “fuck off.” That is the correct attitude for a worrying number of online interactions, and if moderators won’t step up and proactively remove the bigoted propagandist time-vampires who deserve it, the least they can do is stay out of the way. ‘What you chose to say is fucking awful’ cannot possibly be more of a personal attack than being told ‘everyone like you is inherently broken.’
