Sigh.
Morality is defined by an ultimate moral authority, God. If you are a non-believer, then you have no objective moral truths.
Sin is “any want of conformity unto or transgression of the law of God” (1John 3:4; Romans 4:15), in the inward state and habit of the soul, as well as in the outward conduct of the life, whether by omission or commission (Romans 6:12-17; Romans 7:5-24). Sin is not a mere violation of the law of our constitution, nor of the system of things, but an offense against a personal lawgiver and moral governor who vindicates his law with penalties. Some sins in themselves, and by reason of various aggravations, are more heinous in the sight of God than others (Jn. 19:11; 1 Jn. 5:16).
Since God, speaking through the inspired prophets authoring the books of the bible, declared homosexuality a sin, then it is a sin. See: Leviticus 18:22; Leviticus 20:13; Romans 1:26-27; 1 Corinthians 6:9,10; 1 Timothy 1:10.
Thus, homosexuality is just one of a litany of the decay of the perfect moral state found in original creation.
As all sinners, homosexuals can be Christians. All sin is objectionable to God. Since homosexuality is often practiced openly ("in your face"), the reaction by some who have wandered off the “love thy neighbor” reservation is over the top. It may also be the case that anyone that seems to revel in their sin is defiant or disingenuous, if they are a self-professed Christian.
I believe that the true Christian homosexual struggles daily with their sinful nature.

For me, homosexuality is a lifestyle choice, and one that can be rejected with proper counseling.
1 Cor 6:9-11
9 Don’t you realize that those who do wrong will not inherit the Kingdom of God? Don’t fool yourselves. Those who indulge in sexual sin, or who worship idols, or commit adultery, or are male prostitutes, or practice homosexuality,
10 or are thieves, or greedy people, or drunkards, or are abusive, or cheat people—none of these will inherit the Kingdom of God.
11 Some of you were once like that. But you were cleansed; you were made holy; you were made right with God by calling on the name of the Lord Jesus Christ and by the Spirit of our God.
We are not mere animal brutes following our instincts, we make choices according to our greatest desires at the moment we so choose. We are thus,
self-determined moral agents.
Happiness to Christians is more than the needs of the flesh. Active homosexuals must continue to pray for strength to resist their urges and strive to be obedient to the scriptures.
Now on to the point of the OP:
When all is said and done, the issue for those of us who have actually experienced combat up close and personal, is simple: will my fellow soldier in combat do his duty when the time arises? Those who have actually been in combat will know that the man who will not perform to expectations has a certain fate awaiting him. I need not say more, for those that know whereof I speak "get it".
