He was a wolf in sheep's clothing. First he was straight, then he was gay, then he was straight again, founded his ministry, only to find out - oops, still gay.
Well that's ignorant and ad hoc.
More likely, he was always gay and just said that he was straight to hide it.
I don't doubt the power of prayer at all, when done by believers, but when a guy like that's leading the charge, then they're destined for failure.
What this shows is that guys like that are leading these charges. How many of the pray-the-gay-away camps do you think are run by homosexuals and therefore destined for failure?
Don't they look like a scam at face value?
