What? No, we should not force people to share the same space as fascists and racists. It seems ridiculous to have to say it. If I were to encounter neo-nazis in real life, I would not engage in a civil discussion, confident that the police is there to make sure everyone is civil. I would walk away. Online, it's pretty much the same thing. I'm not sure why it's so hard to fathom that most people have more productive uses of their time than hearing what racists and fascists have to say.
