@Bill,
For believers - homosexuality is no different than porn, stealing, murder, hate, masturbation, or any other "unfruitful work" that prevents the believer from developing in the character/fruit of Jesus Christ. If a person does any of the above activities, there is "zero" character development; leaving the believer feeling guilty, wrong and sad or frustrated.
James 2:10
For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.
So - it is not just for a person to judge the transgression of another when all have sinned, before Christ, and come short of God's glory. While we were "in" our sins Christ died for us and we were guilty of "all" sins. This act of judging a person is unjust and unfruitful. And because Christ is not judging you at this time, it's not wise for you to judge another. God is no respect of persons. Under the Mosaic Law Uzziah was judged and lost his life because he sought to prevent the Arch of the Covenant from possibly falling - homosexuals were also put to death. Two extremely different types of sins, but God allowed them to be judged the same. The wages of sin is death.
It sounds like you don't understand the deceptiveness of Satan and how he works. Jesus died and rose so that you and I can be made free of the bondage of Satan. Christ has given us wisdom to recognize how to see Satan when he comes to us. Most homosexual Christians and heterosexual Christians do not fully understand this wisdom, just like heterosexual fornicators (christians) do not understand this wisdom. This is because the emotional pull is the same as any emotional addiction of anything that brings a person into bondage - it haunts and cripples a person. They are confused when their mind says one thing, but their emotions say something different. This is why scripture teaches, "a city or house divided against itself cannot stand. They are confused by the emotional pull dictating how they should feel towards the same sex. Whether it's thought through or on impulse, a person had to be tempted first; and it's through the temptation the deception and paralyzation of the mind comes into play. The addiction overwhelms them.
If a person is not free, they will do whatever it takes to find some sort of comfort from the mental anguish that Satan torments them with. If they believe the only way to get relief from the mental pain is to act as if what they are doing is normal, they will - but it's not to rub it in the face of those that are of the contrary. They are not flaunting it in many cases, just, accepting what they understand themselves to be. Don't be the main character in your post... "Are Christians Killing Christians."
