And then deny membership to homosexuals and get a civil rights/discrimination lawsuit slapped on you. Gay "rights" means allowing the right of people to embrace homosexuality but removing the God-given right of people to tell homosexuality, "go somewhere else."
Gay "rights" is a sophistry. It's about removing rights. When folks like Obama and Romney say they're "for" gay marriage and gay adoption, what they really mean is that they're for punishing churches, adoption agencies, wedding photographers, caterers, etc., that tell homosexuals, "Find some other church/adoption agency/photographer/caterer, etc., to do your event. We'll pass."
Government tyranny -- moral tyranny, as government does this because it deems it immoral to discriminate against homosexuals -- at its most deceitful.
Technically, they can discriminate all they want since they are a private organization, no?
