ulity-choice?

I think this would offend any thinking person. You do not display an open mind, and you discount anything at all (such as the gay gene theory, or in utero hormonal changes to a foetus) which explains anything other than a personal choice. Therefore, I do not think you seek to understand anything, but seek support for a one-track stance. You are not at all confused, that is a ruse to put forth your own rather warped opinion as truth. I feel sorry that you have the need to do this in a public forum.
