Hey Iconoclast, where do you get your bizarre conception of those who are in to Individualistic Nihilism and/or Bonanno in general? I mean, I'm sure that some people who are in to those things like punk, but most people who i know of don't even listen to punk (including myself). I'm not sure why you focus on music so much, as that is mostly irrelevant to peoples political or anti-political interests (unless they listen to political music), you can be a Individualist Nihilist and listen to pop, hip hop, punk, post-punk, classic rock, metal, folk, traditional music, classical, ambient, or whatever else have you. Its as if you view punk rock and Individualist Nihilism and Bonanno's insurectionism as juvenile and just associate the two because of that and a weird stereotype of US anarchists, namely the association with anarchism and punk scenes, which hasn't even been relevant in years as a lot of anarchist have been turning away from punk and the anarchist "scenes" really aren't associated with punk as once was the case.
You seem to assume that all Individualist Nihilists and anarchists interested in Bonanno are male and in their 20's, now there are obviously people in their 20's who happen to have been born male who are interested in those things, but there are also people who are older and people who have been born female who are also interested in them. It seems its the favorite thing to do for anarchists who reject violence and vandalism to equate those kinds of tactics with some sort of male machoness, which to me is ridiculous.
Finally you assume that US Individualist Nihilists don't know about the kind of Individualisms that you mentioned, maybe some people aren't familiar with them, but there are definitely others who are and as has been suggested above, they just don't find them interesting. For instance I've read a few essays from Emile Armand and I've known about those Individualisms ever since I started getting into Individualism, I just never found them that interesting, I've always preferred the Illegalists like The Bonnot gang, renzo novatore, and Bruno Filipi, among others, and people like Enzo Martucci, SE Parker (before they changed their mind about anarchism), Alfredo Bonanno, feral faun/ wolfi Landstreicher/ apio ludd, etc.
