I am unsure what "balance" means when it comes to this topic.
Plan and simple, homosexuality is a sin unto death for any and all who practice it.
Even if the preposterous idea that homosexuality may be genetic were true, I'd say so what. The tendencies of the flesh(ie **** greed gluttony etc) are present in all of us from birth. If we purposely rebel against God in continued willful participation in them, the pursuits of the flesh, we are headed for hell.
I do not understand this tone of near reverence when we are addressing this issue (on the part of some). On more than one occassion, God chose to look sinners in the eye and say "brood of vipers". His goal was simple. There should be no waffling on the issue of willful sin against Christ and His dictates.
When it comes to the message, we should be clear. When it comes to delivering the message, the target audience should leave the sermon, conversation, debate, knowing beyond a shadow of a doubt, that the person delivering God's Word (me, you or any Christian) loves them as Christ loves us.
