During the 60s, supposedly the Hells Angels and the left-wing radicals and hippies were allied in the common cause of the pursuit of drugs and sex. Allen Ginsburg and Ken Kesey were said to have become friendly with the leader of the Angels, Sonny Barger, and his closest associates. They would have giant parties and consume massive amounts of drugs.
Later, the Hells Angels would become symbolic of the end of the 60s with their killing of Meredith Hunter at the Altamont concert (a lot of people probably don’t realize that Hunter was brandishing a gun and threatening the Angels - their stabbing of him was actually in self-defense. But that’s another topic.) This killing became emblematic of the end of the “peaceful” times of the 60s hippie culture and the triumph of brutality, or something like that.
But up until that point, what was the relationship between the Hells Angels and the hippies and left-wingers really like? On the one hand you have a biker gang with a penchant for violence, strong anti-Communism, and a rabid distrust of outsiders - on the other, a loose coalition of left-wingers, beatniks, political activists and other radical types. Did these two groups truly form an intellectual bond (perhaps a love for shaking up the public and rattling people’s sensibilities) or did they just happen to sometimes hang out together because there were free drugs around?
