Do we need to go through this again? I can.
One.) I did not choose it because I was rebellious. I did not choose homosexuality. I did not choose to be kicked out. I confided in my father, was honest, and he kicked me out of the house. So there goes your "rebellious" theory.
Two.) The Bible is not always correct. Genesis 30:37-39, for example, shows the "word of God" has no basic biological knowledge.
Homosexual love is a consensual love between two conscious, consenting adults; capable of choice and old enough to do so. In a necrophilia, only one person may consent, along with bestiality. In pedophilia, the child is -much too- young to consent.
All therapy to 'cure' homosexuality is proven, by 80% of all major psychological associations, to be of great detriment to the homosexual's mental stability, health, and well-being. They advise for all parents and homosexuals NOT to go through any form of therapy for their sexuality.
It's pretty simple it's not a choice, right? I'll add a very, very, important statistic before I jump into the anecdotal/emotional appeal.
72% of all LGBT had no conscious choice in their sexuality. This is credit to the APA (the American Psychological Association http://www.apa.org/helpcenter/
Anyway, to the emotional point, it's just a few questions I'd like to ask:
-Would you choose something, then be scared of telling others about it?
-Did you choose to be heterosexual?
-Would you choose to be kicked out of your home?
-Would you choose something, knowing you'll be bullied by your peers?
-Would you choose something, knowing that it will be of detriment to your education?
-Would you choose something, knowing that you will be hated, refused rights, etc.
