Homosexuality is nature driven. The cause is lack, or expectation of lack of, hot babes. Males in jail, for example, are more likely to be gay.
The cure is of course porn. Porn with hot beautiful babes. That will cure them. We just need more sexy porn and we’ll win them over to God.
If you’re really devoted to the cause, you can also offer your wives, daughters, mothers, and girlfriends to homos or anyone claiming to be one. That’ll cure them. You’ll have big reward in heaven.
