... Are people in this thread actually advocating for vigilante violence? Are people seriously getting dogpiled for suggesting that it is a bad idea to go out on the street and assault people you think are Nazis? And people think that this will end well?
And no, private citizens assaulting other private citizens is not analogous to fighting the German army in WW2.
Edit: To clarify, yeah if you see Richard Spencer walking down the street by all means punch him. If your co-worker starts putting Nazi flags on his cubicle, sure, get in his face about it. But don't get together with your friends, grab some baseball bats, and drive across town to beat down some 15 year old spamming racist frogs on Twitter.
