Violence doesn't work for a political agenda. It never has.
I am distinguishing between the historically offensive violent ideologies of nazis and racists, with the historically reactionary use of violence-as-a-tactic for antifa and black bloc.
The latters use of violence should be stopped, since it isn't helping in furthering the lefts political agenda. We wouldn't be talking about them at all if not for the rise of Hitler in the 1930s and Trump now.
These groups are not all the same level of threats to society. We need to focus on stopping the violence on all sides through better protesting permits apparently, and stopping the fascists and racists from gaining more political power.
I find it obscure how people go on justifying violence when it just happens to feel good with the political agenda.
