"Plain old hate speech" is subjective though.

May I censor those calling for my country to become more diverse? I consider that an explicit declaration of racial hatred and indirect incitement of violence.

May I censor those advocating abortions? I can hardly think of a more violent action than butchering an unborn baby.

I could go on. I'm sure you see my point.

Do what you will with your power, but don't insult us by claiming the moral high ground. And don't expect any favours when the pendulum swings back.
