I kind of lost all sympathy with him when he advocated violence for opposing views. Live by the fist, die by the fist. He's living his own Hell, where his own vices are coming back to torture him.
Still, I would rather meet communists with words, rather than throw them out of helicopters. Don't you see how that's more reasonable?
If Nazis or Communists are actually taking action like fighting/murdering/jailing, then I will join in the fight against them. But while they only use words, even though their words are disgusting vitriol, using force against them only helps their cause and cheapens our own.
On the subject of fighting Nazis, I'll leave you with a quote from Hitler himself, perhaps the pre-eminent expert on Nazis: "Only one thing could have stopped our movement – if our adversaries had understood its principle and from the first day smashed with the utmost brutality the nucleus of our new movement."
