It was a pretty strong dissonance when reading some, let's say, Hunter S. Thompson short story, how "US conventional" some of his view were. Pretty sure it would be the same for any counterculture in any country. A counterculture doesn't actually rebuild its "host" culture from scratch, it just disagrees about a couple of things.
Well said. However, a counter culture can't diverge too far simply because otherwise it will disappear in the fringes of society with only a handful of followers.
A lot of hippies were not vegetarian or accepting of gays, they just wanted to do drugs and rebel against authority.
