> some serious work. The classic argument is really that they should be censored so they can't easily organise and kill us.

There's a difference between words and actions. Words fo not kill. No, words are not violence no matter how much people try to claim otherwise.

Furthermore, censoring people does nothing to reduce a groups ability to kill. Taking away someone's public voice does not take away their capacity to carry out violence. Disinviting a speaker or banning a book does not magically make people's guns disappear.
