i mean in a sense, the sentiment is to make national socialists too terrified to walk into public (honorable goal) but in actuality it devolves to petty vandalism and attacking of people who may not actually be a neo-national socialist.
the problem is that they're trying to organize these attacks rather than keep the national socialist punching an individual act, and have the individual deal with the consequences. it is, legally, a lot less safe to punch a national socialist as an individual, but organized national socialist-punching leads to escalation and collateral damage. i think regular protests should be the group aspect instead. that's kind of weird to say though, because it's not like there's any one 'organizer'.
another important thing to note is people should be sure the person IS a national socialist before they start throwing hands.
