A problem with your argument is .. you use fighting Franco's fascists in Spain as the point in which it becomes acceptable to "punch a Nazi." And remember, all the people who then gave their lives, not to mention all the years Spain lived under Franco - who continued to mass murder so many - for the sake of such apologetics postponing action that could have prevented it to begin with.

So it's fine with me if we punch Nazis. And I'm willing to punch some myself so others don't have to do it for me. 

I'm not willing to put so many others at risk simply for the sake of having a politically correct liberal opinion and being afraid of how some Nazi is going to manipulate public opinion in the press. They didn't have to provide him a forum for his bull, anyway - which everyone knows it is.

BTW, Westneat gave a similar spiel for the UW situation - and someone paid dearly with a bullet that will probably disable him for the rest of his life.

Good for him that he punched him!
