A lot of episodes from the Law and Order franchise seem to draw inspiration from real life events, however, with a recent episode (Law & Order: SVU Season 18 Episode 19: Conversion), I'm wondering whether the writers "jumped the shark": they portrayed a weird "Christian" sect that actually believe in something they call "curative intercourse" - in the words of the character Rollins, they believe "you can rape the gay out of someone".
It seems a little far-fetched to me that this would actually be taught by any group that claims to be Christian, but with groups like Westboro, I suppose anything is possible - is there any group that identifies as Christian that actually teaches any doctrine that resembles this?
