What's stopping them from doing it now? We're talking radical extremists, here. There's not much that would stop them from trying to achieve their goals. The simple fact is, we're trying to turn the Middle East into a mini-America. The history there goes all the way back into the Cold War and the Reagan Administration (maybe farther...I can never remember the exact president that started it...but I'm 99% sure it was Nixon).
See, what peeves me about people saying "it's wrong! it's in the Bible!" and then I go and point out all the other things in the Bible that are silly and ridiculous, I get the argument "but those things are in the Old Testament and Jesus released us from following those laws in the New Testament", so I go and point out the silly and ridiculous things in the New Testament and get the argument "but those rules were good at the time because it was for the good of the people".
Here's my argument back: the founders of Christianity condemned homosexuality because they wanted to have a large population of followers. Homosexuality doesn't produce babies and therefore is a bad thing to them.
LOVE IS LOVE!
