It’s complicated because some antifa are just a different bunch of mindless tribalists.
It really depends if you ended up antifa for social reasons (mainly being part of something) or for having thinked a lot about what are your principles and politics and figured out that haters have to be stopped early, before they get to the stage were they’re hurting lots of people - the latter kind will likely also spot hate replacing reason in themselves and thus stop it before they hurt somebody who might very well be innocent.
Sadly a fraction of self-proclaimed antifa are just another hater mob, just raging against different groups of people than the fascists, which is how you end up with things like cruxifiction-by-social-media against people for the sin of not treating slogans as Sacred Truth.
