This argument can be theoretically solved with the one simple truth that God isn't real. If he was however, I doubt he'd give a monkey's bum hole whether guys were shagging guys or girls or girls were shagging girls or guys. Aren't there worse things for him to worry about like war, famine and that giant meteorite heading for us as we speak?! In all seriousness though, if there was a God, he wouldn't give a damn.
