God has plenty to say about it in the Bible - and His position on it hasn't ever changed. God allows us free choice, even if it's self-destructive - again clearly stated in the Bible. As far as man being unable to say what's wrong with it... how about starting with AIDS? How many millions have been spent on trying to cure and prevent that? That money could have been spent on many other things that could do everybody good - who don't bring on their own diseases by their behavior. Even if you don't believe in God, how can you explain homosexuality if you believe in evolution? They can't reproduce... so they'd die out without an active recruitment program. No matter how you look at it, it's unnatural and shouldn't be encouraged.
