Whew, Ok....let's step back for a second.
I'm confused on some of your statements so perhaps you could clarify some things for me so I can better understand your position. In a post above you say,
My stance: theres a guy, God gives him freedom to do whatever he wishes. The man chooses to follow the desires of his own heart. Somewhere along the way the guy gets involved with homosexual stuff. He falls deeper and deeper into sin, becoming a slave to it.
I'm confused by this because you seem to have missed a few key details that might have some barring on the story. You say that God gives him freedom to do whatever he wishes, but what about the fact that God made him gay in the first place?
I believe you still might be confused (or not convinced) that homosexuality in most cases is not a choice. It sounds like you feel that people are for whatever reason choosing to be gay, but you really haven't explained why a straight person would knowingly choose to be gay. Your only explanation seems to be that some people allow themselves to be a slave to sin.
So I guess the real question is, why would God knowingly make someone Gay, when it is his own law that says it's a sin?
You seem to be saying that the only thing that makes you gay is if you actually follow through on the actions. Does this mean that if I never have sex again with a woman then I am not straight? Does the gay man in your hypothetical idea stop being gay in his "heart" if he never touches another man? How should a gay man pray, would it sound like this, "God, I am sorry that you made me this way, I pray that you give me the strength to not sin, and to forgive yourself for making me how you did, and let me into the kingdom."
I know these are all kind of rhetorical, but I think what many of the people on here are trying to tell you in a nice way is that you really don't seem to have any idea why you feel the way you do. You have one side of a poorly written story and you're basing your entire belief on it. When people inform you that you're missing some of the story, you resort to explaining your "gut feeling" and how that happens to mesh with what is in the bible. The reason why so many Atheists are on here talking to you about this is because you don't seem to have put this topic through a critical thinking filter, done your homework, and come to a conclusion based on logic.
What keeps happening is what often happens when talking to Christians. The conversation turns into nothing more than a few people trying to figure out how to say the exact same argument 20 different ways so that one of them might just make sense. It's like this futile attempt to find the perfect argument and when the Christian just sits there saying, "God did it!" it gets frustrating.
So here is what I suggest, and it is up to you whether you take this advice or not. I think you need to gather as much information you possibly can about this argument before you argue it any longer. I (and I assume many here) will be totally willing to help you find all the information you need to become completely educated on this topic. Then, using that information sit down and come to a conclusion based on ALL the evidence.
Once you have done that, you may still feel the same way about homosexuality, but at least you'll be able to explain why. You'll be able to take the information you've learned and defend your position without fail. I'm not asking you to agree with me, I'm saying that you need to bring more to the table so you can properly explain to me why I'm wrong and if you can do that, you might even change my mind (as I am also a skeptic and open to changing my position if the evidence is good enough).
If however, you're unwilling to do this, then I am not sure you should continue to have an opinion on this topic. The reason I say this is because you are arguing from ignorance and this is not typically a "winnable" position.
