If homosexuality is a choice...then men and women who claim to be homosexual, and behave as such, when faced with being thrown out of their homes by their parents, with descrimination at work or in church, when ostracized by their friends and associates, when faced with violence in the streets etc...should be able to just up and say "Well...that sucked." snap their fingers and then say "Well...I'm straight again" - and go and find someone of the opposite gender and rejoin the majority... free to walk in the sun again without fear of reprisals.
I'm not seeing that happening.
What I am seeing happen is one of four things.
a) People claiming to be gay, acting as such and not being able to 'turn away from the dark side' under any circumstances.
b) People experimenting sexually with homosexuality or bisexuality and finding it wanting, and going back to heterosexuality
c) People who internally claim to be gay, and acting straight (marrying, having kids etc) and eventually discovering for themselves that they aren't happy acting straight and turning to their natural instincts and becoming gay.
d) People who claim to be heterosexual, acting as such and not being able to become gay under any circumstances.
Make what you want of it...nature, choice or nurture....it should still not play into the issue of marriage, law, employment etc...
IMHO - Despite your sexual-orientation, your gender, your race, your salary, your religious convictions etc...you should have the same legal rights as the person next to you.
The quote is "Government of the people, for the people, by the people" and not "...of the people, for some of the people, by the people"
Either the goverment represents all, or it represents none.
