Aren't you the person who made that thread with the Holocaust quiz that made it seem like rainbows and sunshine?
Anyways, regardless of the causation of someone being homosexual, bisexual, or otherwise -sexual, it's not a switch you can turn on or off. It's a matter-of-fact part of who you are and it can't be changed.
Even if it could, it wouldn't matter. There's literally 0 harm to anyone in being a homosexual.
