It's always just been cyclic and continues to be. The era you're calling back to to was just a hard push back against a post-war surge in clean imagery and buttoned up moralizing, amplified by the Hollywood Code, but you need only go back to the early forties to see and hear wide open celebrations of tawdry lives, and can dig back farther again to see repressive times around the Prohibition era, which you might reasonably assumed was in response to a time that was not so repressive at all, etc etc In many areas, we can see the incoming generations being the new teetotalars and moralizers eager to temper things down again. As for the role of feminism, it's found a voice on both sides all along, during all of the cycles. That's its reflection of true freedom. Even during the "Free Love" era and its direct continuance, the Gloria Steinem voices were driving a different vision than the ones celebrating "free love". And in fact, you can see a through line of that tradition within feminism to the one you're critiquing in the present.
