My guess, and it's only a guess, is that same-sex marriage hasn't been "self sustaining" because of religious fundamentalism.<quoted text>
Is it "progression" or simply a passing phase? Why hasn't SSM sustained itself? SSSB is not new, nor is recognized same sex unions, albeit I limited in time and place. Yet SSM never took root to the point where it was self sustaining within the society that allowed it. Are we to think it will now?
Thankfully, we're seeing extremist religions go the way of the dinosaur.
I used the example earlier of how women are more independent, career focused, and even dress differently (they wear pants), than ever before. This represents a shift in societal acceptance of women's roles that I don't believe will ever change again.
I think that our societies are beginning to finally embrace the fact that homosexuality is not a disorder. And if we aren't disordered, then we should be allowed to have access to legally marrying our partners.
I don't think we'll ever go back to a time where homosexuality is seen as taboo and unnatural.
That's my opinion.
