Perhaps in the narrow sense, but not in the grand scheme of things. The reason "things got to the present state" was probably: (a) the success of the women's liberation movement that made a resurgence of societal homoeroticism inevitable; (b) the steady decline of the Christian influence due to its increasing disjunction with empirical reality.
The "gay liberation" movement is just a function of the first phenomenon (particularly of the feminist dismantlement of the intergenderal social compact) and its swift acceptance by Western civilization is a function of the second phenomenon (and part of much broader trend toward rejecting the vestiges of Eastern doctrinaire cultural imposition and reverting to the the Classical rationalist, syncretic norms).
Thank you. Speaks volumes.
