Is Neo-Nazism Relevent?

If someone says "Neo-Nazism" what's the first thing you think of? Probably a gang of skinheads making a ruckus or some sort of protest march. Maybe someone throws a Molotov cocktail, maybe some rocks, and the riot police usually have to break it up.

But the question I've been asking myself is: is that fair? I mean, it's at least understandable: most of what we hear (if anything) about today's Neo-Nazis comes from the news or some prison show. News reports usually go something like "a group of young Neo-Nazis have been charged with..." or "a gang of Neo-Nazis caused a violent reaction with a demonstration today...", and prison violence is probably the only notable result of prison-gang Neo-Nazism.

And more importantly: if the publicity that Neo-Nazis receive is mostly negative, is their ideology even relevant for today's American culture? Would we Americans, who do not happen to be in a prison gang or have shaven heads and swastika tattoos, even consider the Nazi ideology as valid? I think not. Walter Laqueur, author of Fascism: Past, Present and Future states "Small groups in various parts of the world continue trying to revive the old Nazism and Fascism, embracing their emblems and slogans and, of course, their ideas and political programs. But even if these corpses could be resurrected, they would still be irrelevant to today's world. Just as Communism in its Leninist-Stalinist incarnation cannot be resurrected, historical fascism cannot have a second coming, either." (4)

Is Laqueur right? If he is (and he sounds pretty convincing), what reason, psychological or ideological, could the members of the groups that attempt to resurrect the Old-World Nazism or some of its parts have for what they are doing? Obviously to them Neo-Nazism is relevant. I'm talking deeper than the mindless violence: why, to these people, is Neo-Nazism relevant? Do you think that the American culture could ever be swayed towards the ideology of these people? Why do Neo-Nazis believe that it's possible?

I need to do more research, obviously, but let me know what you think.
