Some violence is self defense, like in this case. It may not be our favorite thing, but if you're up against fascists in power the only thing that can stop them is violence. If you don't, you're just letting them genocide literally everyone they want, which isn't just extremely cruel and abominable, but it's also stupid, as the enemy of the state is a moving target and for every genocide they accomplish they move on to the next. It's a matter of time until you or your loved ones are declared the enemy. What then? How can you resist genocidal violence if not with self-defense?
