I explained that I was out of time and don't like this debate. However I will respond to this post for the heck of it.
Even if we get oriented before we are born you wouldn't know it. It is unknowable. We are not discussing what we each remember being attracted to. The issue is how you can know that we get oriented before birth. Why is that even relevant?
And our bad decisions are rightly condemned. You might want to walk this line of reasoning back. Why shouldn't we have television adds against being gay the way we do against getting fat? However I condemn gluttony as well. At least I am consistent. Why are you for one destructive thing but not another?
Homosexuality is not a "destructive" thing. Smoking, excessive alcohol consumption, consuming crap food, choosing to be a couch potato are all choices. Sexual orientation is NOT a choice. You are far from "consistent." In fact, until I pointed it out to you, you were defending those who were sick (both those who made bad choices that got them sick and those who simply had the bad luck to contract an illness that was not due to anything they chose to do or not do) and saying that the financial burden of those who chose to abuse themselves didn't matter.
Perhaps you are the one who should "walk back" your line of thinking? I hesitate to call it reasoning, since it's quite obvious that you have not reasoned on anything whatsoever. You simply hate homosexuality and refuse to consider anything but what you want to believe.
Let's discuss your question about knowing that we get our sexual orientation before birth, shall we? You have been asked multiple times to inform us as to exactly when YOU made the "choice" to be heterosexual and be attracted to members of the opposite sex. You have refused to answer. Why? Could it be that you know for a fact that you never had to choose? Could it be that you simply were attracted to members of the opposite sex and never gave a thought to being physically, sexually or emotionally attracted to someone of the same sex?
If heterosexuals don't have to make a conscious choice about their sexuality why do you state that homosexuals "choose" to be gay? This reminds me of a conversation I had some time ago with a gay friend. She lived in Kansas at the time and had tried the "marriage cure," which, not surprisingly, did not work. She said to me, through tears, "If homosexuality was a choice, I would NEVER choose a sexual orientation that would cause me to be hated and one that would make me fear for my life. If I had a choice, I would definitely choose to be heterosexual, but I can't."
Perhaps you should try to walk a mile in someone else's shoes. Think about how it would be to be hated simply for loving the "wrong" person. Think about how it would be to be afraid that someone might kill you simply because you held hands with or kissed someone you love because those murderers believed as you do that homosexuals should be "eliminated" and that "God hates them."
