Since Freedom of Speech is one of America's basic four freedoms, I couldn't deny anybody their right to it, distasteful though I might find it. But, as others have posted, nothing is achieved with confrontations. I would attend a pro-active event, like a "love-in" at a park, to celebrate inclusion and peace, while the neo-Nazis across town give their speeches to...nobody but themselves. Or a fund-raiser for an anti-racism organization, like the town in Germany that gets people to pledge money for every mile the neo-Nazis march through their town, so the Nazi sympathizers are greeted with delight and people holding up signs thanking them for their contributions to anti-racism causes. But directly engage angry, resentful men carrying weapons? Uh, no thank you.
