Yes, and? Do you think everyone who subscribes to Nazism has stubbed the toe of a single person, let alone kill someone, let alone commit genocide? Most of them also only want to kill people, and violence is not solved with more violence. That just leads to a warring and unstable society,and an escalation of levels of violence. This can be avoided if you use non violent methods, like those mentioned in my other comment.
Use violence when they have started WW3. Not when they are peaceful members of society not causing any harm to people. Can’t you see the difference between when they are killing people and when they are keeping to themselves?
