Let me say it very slowly for you:
1. You think sexual attraction is a matter of choice for gay people.
Is sexual attraction likewise a matter of choice for miserable people??
But to respond to your accusation: It doesn't matter what I think; I've already explained to you why this particular fixation of yours is irrelevant. For sake of moving past this fixation of yours, regardless of whether your fixation is correct or not, I'll just grant you your position that there are in fact some men in existence who are helplessly attracted to other men (meaning that they will only ever see and think about other men "in that way") ... SO WHAT?
As I've already said previously, it doesn't matter whether or not one is capable of controlling what specific desires one experiences. What matters instead is how one chooses to respond to the presence of those desires. How one chooses to respond to one's desires is the exact same regardless of whether or not one has any control over initially experiencing said desires.
For instance, you don't HAVE to actually steal money from your brother simply because you experience a desire to do so. You can instead FLEE from your desire to commit theft. Likewise, a man doesn't HAVE to have sex with another man simply because he experiences a desire to do so. It's all about how you choose to respond to the desires that you are experiencing. If you find that you struggle with following God's will, then pray to God and ask him to help you follow his will for your life rather than getting caught up in your own (often misguided) desires.
2. You don't feel like YOU had to make a choice to be straight
See my response #1. I've already explained to you why whether or not I happen to have any control over experiencing sexual desires about women (or even about other men) is irrelevant.
3. ERGO: You believe gay people were born with the requirement to choose their sexuality but you were born "normal" and didn't have to choose.
Why are you under the impression that I'm not gay? Rather, I consider homosexuality (men lusting after and having sex with other men) to be an abomination unto God, as the Bible says that it is.
This isn't about "sexuality". This isn't about "being able to choose the specific desires that one experiences". This is about choosing how one responds to the presence of those desires.
IOW, this isn't about "being (identifying as) a thief". This isn't about "being able to choose whether or not I experience a desire to steal from others". This is about choosing how I respond to the presence of a desire to steal from others. Do I succumb to my desire and steal $100 from grandma? ORRRR do I resist (or otherwise flee away from) my desire to steal from grandma, choosing to instead visit grandma on a day that I'm not angry at her?
4. God decrees that gay relations are an "abomination"
Incorrect. God is actually very pleased with gay relations. Rather, it is homosexuality that God considers to be an abomination.
What this means is you worship a God who put a stumbling block in front of gay people that he didn't force you to have to go over.
Incorrect. God does NOT tempt people to sin. (James 1:13)
Yet we are told this God loves all people and would NEVER create someone for the express purposes of torturing them forever.
He DOES. For the sake of reconciling humanity with him, he came down to Earth, was born of a virgin, lived a completely sinless life, was wrongfully persecuted for it, and willingly suffered a wholly undeserved and unfathomably cruel torture and crucifixion. If that's not true love, then I don't know what is.
That makes your God logically inconsistent.
Your logical fallacies are your own fault, not God's.
