i wouldnt call it fascism cause they arent in power and really silencing anyone, but yeah they're dumbasses who think hurting people makes them more likely to stop having their beliefs
the thing is this kind of approach towards opposing beliefs (aka doing something that only makes them reinforce said beliefs and also hate you) is pretty common on both sides. this is just one of the more extreme and violent cases.
