That's some stupid fucking logic.
"Durr hurr if people are gay it'll lead to extinction!"
Yeah, cause EVERYBODY IS SUDDENLY GOING TO BECOME GAY IF WE ALLOW GAY MARRIAGE! Oh wait, no. That's a fucking stupid suggestion. It has absolutely ZERO logic to it. Besides -- you stated that a gay man and a lesbian woman can have kids. If gay people can have kids that way, it won't lead to extinction, now will it?
