Let me tell you a little something about what's not natural. Digging up tons of crude oil, processing it and pumping the result into the atmosphere - that's unnatural. Polluting the night sky with artifical light. Dumping all sorts of shit into the ocean. Mankind's modern existance is completely out of balence with nature - very few people have a problem with it, they're called radical environmentalists.
Homosexuality? Well guess what,
it's perfectly natural. It's just conservative Christians with issues to press unfounded fears that have a problem with gays. The reality of it is, you're probably more likely to have your life cut short from POLLUTION than anything gays do. And as a conservative, you probably don't take much issue on pollution. It's great to have misplaced priorities.
