I know this is the Bible Belt and all, but surely your god wouldn't pass it up in the process. From what I've read, there is no differentiating levels of sin. There is sin, and not sin. No in between
Sin is sin. There is a difference though between living a life of sin despite what God says and commiting sin and then humbling yourself before God and repenting.
If being gay is not a sin then gay people will not humble themselves before God over it. IF it is and they see nothing wrong with it they go against the will of GOd. to each his own, but its a very interesting theological debate.
