Eventually the Gay rights movement will win out.
Like it did in ancient Greece?
And how did that turn out? Oh, right. Slippery slope. Ever see those attic vases with a bearded man courting a young boy?
And finally lets not forget that their fight is a lot closer to our fight than many people on either side would like to admit.
Nope. Sorry, I like women and only women. And I think marriage as a societal institution is worth preserving. Their radical agenda has nothing to do with anything I want. In fact, it's diametrically opposed to what I want.
Lots of people from teens up through twenties and up the entire age scale feel as I do as well, so your side is not going to "win" anything, especially if you keep obnoxiously pushing hard enough to cause backlashes, especially if your "pride" parades are nothing but "squick the mundanes" freakshows of bondage, sadism and masochism on public streets.
Deal.
(BTW, some people need to look into the extremely gay-friendly Provincetown, where their so-called friendly gays angrily shout "breeder" at straight families with children. As if that were a slur.)
