If a gay dude acted straight for enough time, I suppose he might become straight because of the fact that homosexuality is an unnatural thing caused by modern living.
God loves everyone. That's why homosexuality is bad, it's because it also harms those people who are homosexual. It sends them to hell, and that's bad. Therefore, if I love gay people, then I don't want them to be gay. There you go, in simple terms.
So you're telling me that if I were to tell you that I were going to jump off a cliff and started walking toward a cliff nearby, you wouldn't stop me? After all, it's my choice to jump off a cliff.
