Have gay people ever turned straight?
FWIW, I only know 3 gay people, and all of them later in life worked out their life issues and realized trauma from childhood (in this case it was molestation for all 3) had made them gay - they are all straight now (well, one chick is mildly Bi).
This is why I laugh when people throw out the 'Well they are born that way' reasoning to justify pro-gay policies, making it sound like all gays are that way.
