It really baffles me how people want the community, or even worse, the state, to respond to neo-nazis and company. It was mere months ago that the government flipped from the maybe-kinda-neoliberalism-maybe-not of Obama's Democrats to the balls out nativism and demagoguery of Trump's Republicans. No government where ideological shifts of that magnitude are possible is one where someone should seek to assign "shut that shit down" as an acceptable card, the same goes for popular culture.
It's a cheap rhetorical tactic as well. "Look at bad thing, how can you suffer the existence of bad thing? Can't you see that bad thing is going to magically suborn all society if we do not take Action? What are you, some kind of bad thing lover?" Literally McCarthy. That fascism is actually a bad thing doesn't change this, it's a thoroughly unhelpful chain of thought.
There are two things that matter for adjusting the future path of society. First is winning common and culturally-backed support, second is adjusting the structure people live in to encourage positive developments and discourage negative ones. Getting in street fights with reactionary dumbasses acquires neither of these, and I could see an argument that it actually goes against both.
In addition, political nonviolence is a highly, highly desirable quality over political violence, and is about equally as hard to obtain. To place such a thing at risk is immensely unwise, especially in light of some of the politically violent places we can see from here. The only acceptable political violence is self-defense, and if you're seeking out or preempting conflict it stops being self-defense. A good guide is the practices of contemporary antifa versus the Black Panther Party. In spite of what popular culture suggests, the latter were often immensely exacting, memorizing the law as written and using that to their advantage. They also performed services for the community, most famously free breakfasts for children. This, in spite of being about as far-left as antifa, is perhaps one of the clearest guides of how broken antifa really is as any sort of activism.
