having gone to burning man a few years ago (once only, but 10 days there gives one quite a bit of insight into the attendees and the activities), i wish to lay to rest some misinformation in the above posts:
1) MOST of the people at Burning Man are NOT hippies. if anything, they are primarily ravers, artists, and/or partiers. and honestly, there's upwards of 40,000 people that attend each year, to call them all "hippies" because they prefer to think, act, and dress outside of what's "acceptable" or "the norm" (or because YOU don't like it)...is childish. and most of them don't go around trumpeting how "anarchist," "hippie," or "alternative" they are, even if their dress and behavior gets them labeled as such.
2) Aleister Crowley was not an anarchist nor did he espouse a philosophy of "random, willful acts" i.e., what most people think of as "anarchy." among many other things, he was a mountaineer, an extremely intelligent and educated person, a fiercely independent and revolutionary thinker, and someone who despised belief systems which encourage sheep-like behavior in their adherents (Christianity being the most obvious example). he was also egotistical, overbearing, and probably difficult to be around (like many Westerners, oddly enough), but he was not an advocate of "anarchy" in the popular sense or of "random" acts of violence, as the above poster implies. perhaps if people would make the effort to read up a bit on who "The Beast 666" really was as a person, they might discover that he wasn't really that scary of a bogeyman at all, just another person with many points of view that they might or might not agree with.
3) people can despise the police and still see the value (in principle) of having them around. true anarchy is as much of a pipe-dream as "true communism" or "true capitalism". people who are raised their whole lives in the structure of a society that has order and authority (most people in industrialized nations) have that way of thinking deeply ingrained into them, and to expect them to be truly free of it just because they go to a gathering in the desert for a week is foolish. OF COURSE there's order and structure to it, there HAS to be for it to work. for example, the Black Rock Rangers: a populist police force that works with the "official" Nevada and U.S. authorities to keep things from getting dangerous. it is necessary to have such structures, the difference is in how they are implemented. people hate the police because so many of them abuse their power as much as because they hate the "idea" of police. plenty of those who profess to "hate the pigs" are glad they are around when they find themselves in a situation where the only thing that stands between them and injury or death is the power of an authority figure. (myself included, as experience has shown me.)
