As BTS said, he would walk out. He is a religious man that looks to the bible for answers, as over 1 billion others do.
The bible may indicate that homosexuality is immoral, but it does not justify humans taking "the law" into their own hands, so to speak, and punishing other humans(making outcasts, bullying, abusing, killing)....well at least the "New Testimant" doesn't justify that....hmmm, kind of confusing.
Well worth discussion.
While the discussion/dialoge continues, I'll let "god" be the judge, and until it's clear, I'm working on treating my fellow man like I want to be treated.
