This poster on Reddit said it better than I could, and I think he's right;
All you people so gung-ho about punching Nazis: go do it. See what fucking happens. Go to one of these rallies and just cold cock one of these guys in the face. Do you think he's going to get back up and say "Oh now I get it! I shouldn't hate non Christan whites. Man this whole racism thing sure is silly huh?" Do think the rest of the rally is just going to stand there and let it go without incident? You you think these people aren't just wanting to bait you into violence just so they can respond with another car ramming into a crowd? Or maybe they'll use those guns for more than show next time.
You think you won't make these people more radicalized by threatening violence to silence them? You think you won't be justifying their narrative that the left is out to get the white man? And how far are you willing to take this? What if punching them doesn't stop them? Why not just put them in camps, deprive them of their rights, and keep their horrible ideology separate from the rest of us? Fuck why not just kill them? They're just Nazi scum. It's not like they're people or anything. And who's to say who a Nazi is? Are we all just going to agree on some criteria? Are you just going to just decide for yourself? Do any of you think you have the moral clarity to be judge, jury, and exucutioner?
Nothing good will come of this. You will only contribute to the problem and put more lives at risk. They are horrible people with a horrible ideology, but they have every right to say it. And you have every right to denounce them in the harshest possible terms. But you don't have the right to maim and kill your fellow man because you disagree with them. Let law enforcement do their jobs and deal with the criminals in these groups that break the law. This violent, unconstitutional brand of street justice isn't the path we want to go down. And it isn't what any reasonable interpretation of Captain America would want you to do. -BookerDraper
