Moral scorn is not the only argument against sodomy.  The overwhelming percentage of HIV/AIDS, sodomy, and gonorrhea in the male homosexual population would be one of any number of public policy reasons for making sodomy illegal as it was for the country's entire history.

Religious morality is typically a function of the evil and heartache that results from committing certain acts.  God's will is quite obvious as all religions over time have considered homosexual acts sinful.  It's not mere happenstance that the AIDS crisis occurred just before Lawrence was decided.  But the lust of men is not easily overcome, even by God.
