True Left

In fact, I consider it a mistake on the part of the early Counterculture to be uncritically associated with the sexual liberationists. Sexual traditionalism definitely deserved to be attacked, but I would have preferred the attack to have been launched from the angle of romanticism rather than that of hedonism.

And it was the usual suspects who strove to make hedonism part of leftism and the counterculture:
