banning political speech, no matter how full of shit, would only cause problems in the long run, and so it has.

I really cannot follow the argument. In Germany, we have a law making it illegal to deny the holocaust. People will say that seven million jews never died, and the police will investigate them, they are taken to court and put into prison if necessary.

Nothing bad ever came from this. We simply get to put one specific kind of asshole into prison if they spread lies to sow hatred.
