If their goal was not to protect people but to kill nazis, maybe they were doing something wrong.

Are you seriously saying prioritizing stopping a genocidal maniac from destroying the world is wrong? Seriously?

Anyway, it’s different in wartime. We are not in wartime, and modern day people who believe in Nazism are not killing people

Not for lack of trying. Or have you not noticed all the mass shootings? They need to be stopped before it gets worse.
