No, I didn't say it was genetic - I believe much male homosexuality to be caused by factors in utero. Which may be influenced by genetic factors. There is quite a bit of evidence for both of those points. Does that mean it is settled science, one way or the other? No, that's not how science works (slamming "climate experts" here).
And, the idea that no one has discovered a definitive genetic cause doesn't mean one isn't there; just means one - or many - haven't been discovered yet.
And, yes, @mirraflake was using anecdotal evidence to back up his understanding and did so quite well I thought.
Even if he did it well, it is merely a few cases of which he is not privy to all of the information.
"Scientists" have been working very hard to prove their leftist agenda, and yet have failed. It is an effort to blame God (it's been done by liberals even on this board) for homosexuality, and for those who don't believe in God, an effort to prove that it is "normal" because it's inborn.
What IS inborn, in every single one of us, is a bent to sinning, and each of us need to work on NOT doing what is Scripturally forbidden. Not just homosexuality (which is in as bold letters as any sin is), but other forms of lust, lying, gossip, hatred, sinful anger, theft, selfishness, greed, and every other form of sin.
"For ALL have sinned and come short of the Glory of God." Thankfully, we have a Savior, who took our sins on Himself, so that we don't have to be burdened with them. (I know you believe this, and it isn't intended as a sermon to you.... just a conclusion to my thoughts here).
