Hooligan-like countercultures are also excluded as far as "think" or "independently" goes for an obvious reason.
Thus, the only independent thinkers I've encountered are individuals who don't aim to have all the answers, who can accept disagreements, who attempt to know themselves - but those are individuals, not countercultures.
I'm erring on saying that countercultures were never about independent thinking. They were about fitting in with different people.
