I have always had this vibe to from them- It's one thing to be best friends, but they seem to be more than that.
I think it's their way of mocking. If he was gay, I don't think he'd be devoted to a church that thinks gay people need to be cured. His friends are the same way. You could chalk it up to his parents forcing him to go to a private Christian school when he was younger, but he's nearly 21. He chooses to love a church that teaches that gays are "broken" and perverted.

That's what Jeremy loves. Someone that is gay doesn't spend their time listening to that crap like Jeremy does.
