The article written by Karla Mantilla makes some damn good points.
I like this quote best:
<< I know someone who believes he was born to have a sexual penchant for wearing lacy silky women's underwear. But, come on, how could that be biological? >>
<< But this is the point. Homosexuals choose to be homosexuals because something about homosexuality appeals to them, they like it, they prefer it to heterosexuality. When this is attributed to biology, any further examination must stop there. Why do some people prefer same sex partnerships over opposite sex partnerships? What seems preferable about it to them? What don't they like about heterosexual relations? That is the rub right there. What if there are reasons that people reject heterosexuality and embrace same sex relations? What reasons would people have to prefer same sex relations over heterosexuality? Calling it biology does not allow us to even ask the questions. >>
