gays don't decide to be gay....
I have known a number of homosexuals, and many of them were born that way. Homosexuality has been with us since the beginning of time, and will be with us til the end of time. To say it's a choice is just cherrypicking facts to suit Dobson's agenda.
Birth defect, mental illness, or a choice... pick one...
The behavior IS a choice, not the attraction to the same sex. It's an abnormal attraction NOT to be succumbed to but overcome just like any other abnormal attraction.
