A quick Google search isn't returning much, but it's hard to find a good set of terms to search for. I recall spending a lot of time in a class talking about it, though. At once point we were given quotes and asked to identify them as being either MLK or MX, and, not surprisingly in this context, all of the quotes about avoiding violence were from Malcolm X, and all of the ones demanding violent revolution were Martin Luther King.
Also remember the duality of those two people: Martin Luther King at times called for violence and Malcolm X was mostly a peaceful protestor. It's easier to put them into categories but nobody is so bluntly one way or the other.
Just as I hear Paul Graham's name blasted frequently online, for a variety of reasons, I'm certain Naggum inspired as many people as he scared off. Never assume an internet personality is the whole story.
