I find it very easy to believe. I suddenly discovered that I was heterosexual at age 13. Prior to that epiphany I was completely happy without girls in my life, and prefered the company of bicycles, G.I. Joes, bb guns, and other like minded boys.
However, one day, and I still remember it with clarity, I was watching the Sunday matinee on channel 13 with Carmen Cleary. The movie was 100,000,000 years B.C. Something in Raquel Welch in that fur bikini literally jump started my libido which had lay dormant for 13 years, and immedietly after it happened, even Carmen looked good. After that, I never once preferred the company of a male over that of a pretty girl, even for conversation.
I have a much easier time believing that kids are being recruited.
Trust me, I know many,many gay people. Not one has ever said they were recruited.
