Does Antifa participate peacefully in protests?
As far as I know about their philosophy, peaceful protesting is not their tactic.
From what I have read and heard (from their own mouths) about their beliefs is that they believe in "preemptive self-defense" which allows them to come to a protest with violent intentions and think it is moral to do so to deter some anticipated "future" violence.
I'm not sure if the black-bloc is the same but they did the same things years ago with masks, weapons, fire, and projectiles. Same look, same MO. Europe and America. (recall the WTO protests in Seattle)
It could be the case that I have only seen the violent videos but I cannot find a large peaceful protest where Antifa showed up in good numbers and were not violent and/or destructive in their behavior. Can you?
