Gee. I can't imagine being anything wrong with what you're saying. Except, of course, for the following four or five paragraphs:
"It ended the Roman empire" No, immorality and decadence ended the Roman Empire. Bankruptcy didn't help, either. I don't see any gayness fucking anything up, here.
"Hitler's Germany" I see getting the crap bombed out of you by America and listening to an end-stage syphilis patient killing this empire. Weren't the Nazis on your side, dude? They killed over 500,000 homosexuals. Get on the ball.
"Stalin's Russia" I'm going with everyone else's answer on this one: Stalin dying killed Stalin's Russia. And didn't the USSR outlive Stalin by a handful of years? Obviously, the queens are afoot. XP
"and Sodom & Gomorrah..." And the Land of OZ, and Fraggle Rock, and the fucking Smurf Village. They're all gone, now, and I'm not sure that any of them existed. Well, maybe the Smurf Village did...anyway, all destroyed by the fags. Sure. And one more thing: let me inject you with some AIDS infected blood. If you're right, and God loves straight people, then you won't get infected. Unless you're gay. Right.
"...and it will be the destruction of the US if we continue down this moral slippery slope." All the Christian Black people, and the Haitians, whose AIDS population eclipses the gay AIDS population tenfold, or the skin-poppers, should have the right to marry. What harm could they do?
Asshat.
