A great deal has been said about Hunter S. Thompson's impact on American culture and journalism. After his passing, there were numerous depictions of him. Some regarded him as a brilliant innovator of the written word, while others labeled him an egotistical madman who cared more about himself than the story.
All I can say is that anyone who actively seeks the company of men like the Hell's Angels is either brilliant or crazy, and I'm inclined to believe the former.
This book is fascinating for many reasons. For one thing, it poses more questions than it answers. Some of the simpler ones are covered quite well, such as where the Angels came from. There are sociological theories, psychological theories, and economic theories, but Hunter doesn't really bother to try and determine which one might be the best. Another question that lingers throughout the entire book is what we should do about them. The answer, as far as I can tell, is to keep a loaded gun around the house and hope they go away without breaking too much stuff.
There's no doubt that the Angels have earned their reputation for raising hell, but Thompson writes as if that reputation has taken on a life of its own - we created the Angels as they are today from the seeds they planted. From his observations, there's no real agenda for the Hell's Angels - they don't want to overthrow the squares, they don't want to destroy the world that has wronged them. They really just want to drink, take drugs, and have fun, and if they were the only people in the world, they could do that without anyone getting stomped.
Unfortunately, there are other people in the world, and it's very difficult for everyone to coexist. "Normal" society can't deal with the strange ethos of the Hell's Angels, and the Angels can't compromise their ethos for society's peace of mind.
Thompson follows a group of Angels around for a few months, observing them play, party, and fight, and the impression I got from what he wrote is that for all their savagery and menace, they are an inevitable product of modern America. There's no single factor that can explain them, but a combination of events and influences that came together to give the Angels a chance to exist. All we, the squares, can do is get out of the way and hope that America changes so that it no longer needs the Hell's Angels. If history teaches us anything, though, that day is a very, very long way off....
