Life Cycle of Pride Movements

I interested to know if there is some kind of a life cycle that has been described for "pride" movements. For example, when I was a young woman, the feminist movement was just getting off the ground and was relatively powerful. Although not all women considered themselves to be feminists, those who did were very vocal and focused, with a fairly clear agenda.

But now, I don't hear ANY young women describing themselves as feminists, although they all enjoy the benefits that the early feminists won for them. It seems obvious to me that there was a period where the notion of feminism was rising and gather steam, then a period when it had enough strength as a movement to effect changes, and then a period of decline, during which most of the societal changes persisted, but no new changes (such as passing the ERA) were able to be accomplished. Does this process actually exist, and can it be used to describe other "pride" movements?

If such a process exists, those of us who are supporters of particular social changes and their associated pride movements might modify our strategies based on where the movement was in the life cycle.

Any thoughts?
