Majority of this site, likely including you, probably don't support absolute pacifism.
Unless you are on the trivial fringe that subscribes to it, the question is always not whether violence is required to protect yourself, it is at what point and against whom is violence required, and what are the rules around it.
Fascists so far have a track record for at worst, killing a few million people, and at best, absolutely ruining the countries they have managed to take over. Their movements have historically not been bound by any law, including their own.
