Isn't perjury a crime? What about death threats? It's all speech, and it's the type of speech hate groups use - the type that is already a crime and we want to protect under some strange interpretation of the first amendment to your constitution.

If a group is threatening the security of non-white people, some even going to the extent of carrying guns (as is their right) whilst they make said threats and spread lies, I don't know what else you need to shut them down.
