Theirs a big difference there. In drinking, you involve others into your habit and possible harming them ... drinking away the family money ... drinking and driving ... domestic violence, ect. In following your sexual orientation, who are you harming? You're shaming your family
Big deal! There would be no shame without the stigma that WE, as a society, have attached to the matter. WE have MADE that abnormal behavior, not the Bible. Their families should love them anyway.
