Why do religious people not approve of homosexuality?

[Sui]

Well, my two cents on the subject are this:

Religion wants straights so they can reproduce.
The reproduction creates children, who are drawn into the religion.
The children grow up and create more offspring to follow the religion.
The cycle continues.

So basically it's more or less the same thing as breeding livestock for food. Well, minus the whole food thing, and adding power instead. Because everyone loves a good theocracy.

But whenever some religious prick gets on me, if it's a guy I follow Ron White's example.

"You look at porn right?"
"Yeah, so?"
"You like hardcore?"
"Heck yeah!"
"Do you like the guy to have a little prick?"
"OH HELL NO, I like him to have a big throbin'..."
[insert sly grin here]

and every person I've met follows that template... if they dont', I start questioning them about what's so bad about it. Usually it's "god has condoned it". Well, then I ask if god has said that a mass genocide of humans should be set forth, would they follow and do it anyway? At this... most go silent... some try to recover by saying "Oh god would never do that..." riiiight... How do we know this god guy isn't just playing a sick game of cat and mouse with us? hehe... just little playthings... mwahaha..
