Just to add a quick point here, the Bible calls homosexuality more than just sin. It is called an abomination.
Lev 18:22 Thou shalt not lie with mankind, as with womankind: it is abomination.
Lev 20:13 If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them.
Blah blah blah blah
Every time anything about gays comes up, there is someone who wants to quote scripture.
You have brought nothing to the discussion, all you have done is quote something that you believe in and are using that as ammunition against gays being married.
Here is the solution:
All the people who believe like you do, keep on doing what your doing, but you and the rest need to let the rest of Americas free society believe and do as they want also.
If two guys or girls want to get hitched so be it, mind your own. If they are not actually physically hurting you or finacially hurting you, it is none of your concern.
For some reason the religious folks who love their freedom to worship as they please have no issue with taking freedoms from anyone they deem unholy or in this case an abomination
