Gay rights was a political topic... two decades ago.
I hate to be the one to inform you of this, but you lost the culture wars on gay rights.
Gays can marry, serve in the army, adopt children, have their own children via surrogates, and as technology/medicine improves there will be even more options.
Not even a far right supere court is considering overtiring gay marriage, and despite some public moaning the Republicans don't want them too because it has been a vote killer for them for over a decade and they're happy to see the end to this debate.
You are confined to the contingent of crazy old crackpots - the old people who are still upset about black and white kids going to school together, evolution being taught in class, girls wearing pants - decades after everyone else stopped giving a shit.
It's not political to show a gay marriage anymore because your side lost. Completely.
Go live in Russia, China or some 3rd world shithole if you hate gays so much. I'm sure you'll love it.
