Reading this thread has been... Surprising. I did not even realize that political violence has such a huge approval rate among CFC members. A few things to note, if I may:
First of all, political violence is highly problematic. The guy who was getting punched, is he really a nazi? Or is he a nazi in the same way that Trump is Hitler (meaning that he isn't, but his political opposition uses that term to slander him)? Even if he is a nazi, does he not have the same rights as everybody else, even if his views are detestable? Turning to political violence seems like a bad idea to me, not least because it is a slippery slope.
Second, we already know from history that "punching nazis" does not work. Nazis were able to gain power in Germany, but it wasn't because of any lack of punching. In fact they got harassed a lot, and in response, they created the Nazi brownshirts to protect them (the brownshirts' mandate quickly exceeded merely protecting their rallies however, as the political violence escalated). In any case, it's not that there weren't violent opposition to nazis back then, there was. It simply did not stop them.
Third, all of this is highly counter-productive. I don't know who that guy, who was getting punched, is. But he has gained a lot of publicity because of this. And even though the publicity is negative, he's still getting it. I can easily imagine him getting at least some new fans that he wouldn't have otherwise gotten. Simply put, punching him doesn't seem like a good strategy. It gets even worse when you consider how this makes you people look. This "evil violent nazi" is minding his own business, conducting an interview (did he explicitly call for violence?) while "the tolerant and peace-loving left" punches him in the face. And then 75 % of the left cheers on and explicitly supports this display of political violence. Whatever happened to the hippie left? Put flowers into gun barrels? If nobody gave a hoot about this guy, then nobody would give a hoot. I find it hard to believe that he is any kind of real threat to democracy.
