Human Dignity?

I was watching a Sunday talking heads show this morning, and of course one of the topics of discussion was the Supreme Court's recent decision to make same-sex sodomy a constitutional right. In typically evading any discussion of the Court's end-run on Tenth Amendment, and the fact that there is no right to privacy in the Constitution, one of the left-liberal talking heads said that he supported the Court's decision because the law in question had "oppressed" homosexuals by depriving them of their human dignity. I heard this and thought to myself, how is a homosexually oriented person's dignity being suppressed by a law that prohibits behavior that is intrinsically undignified? Sad is the day when our society and culture includes within the standard of human dignity conduct that is both biologically and morally unnatural. Oro pro nobis.
