The Bible acrually speaks against homosexuality quite a lot...
Leviticus 20:13 ~ If a man lies with a male as with a woman, both of them have committed an abomination; they shall surely be put to death; their blood is upon them.
Jude 1:7 calls it an unnatural desire
But I like Romans 1:26-28 the best...
For this reason God gave them up to dishonorable passions. For their women exchanged natural relations for those that are contrary to nature; and the men likewise gave up natural relations with women and were consumed with passion for one another, men committing shameless acts with men and receiving in themselves the due penalty for their error. And since they did not see fit to acknowledge God, God gave them up to a debased mind to do what ought not to be done.
