When you say it’s ok to censor something because it is [hateful | racist | sexist | obscene | dangerous], then you’re opening a pretty bad door. You’ve declared it ok to censor—now we’re just arguing over the list of adjectives worthy of censorship. It doesn’t take much to add things like “embarrassing to politicians,” “profit-destroying,” or “against popular opinion” to that list. Who knows, you may hold what you think are benign beliefs and opinions today that someone deems censorable tomorrow and there will be nothing you can do about it. No internet for you, round-earther!
