Here's a conversation you can have, right now, with anyone who claims to be an "ex-gay."
DCEIVER: So let me get this straight. You sang some songs, recited a bunch of poems, and you aren't gay anymore?
EX-GAY: That's right.
DCEIVER: For real.
DCEIVER: This stuff actually changed the way your dick gets hard.
EX-GAY: Hoo, boy, did it ever.
DCEIVER: Well...okay, I guess. I mean, what do I know? Say, would you like to come back to my place for a three-way?
EX-GAY: Fucking Christ. Would I ever!
