Not that I’ve been reading supreme court opinions or anything but Scalia’s dissenting opinion basically says that the decision in Lawrence V. Texas means that Same Sex Marriage should be legal.  Excerpts below, bolding by me.

Justice O’Connor argues that the discrimination in this law which must be justified is not its discrimination with regard to the sex of the partner but its discrimination with regard to the sexual proclivity of the principal actor.

[…] This reasoning leaves on pretty shaky grounds state laws limiting marriage to opposite-sex couples. Justice O’Connor seeks to preserve them by the conclusory statement that “preserving the traditional institution of marriage” is a legitimate state interest. Ante, at 7. But “preserving the traditional institution of marriage” is just a kinder way of describing the State’s moral disapproval of same-sex couples.

[…] One of the most revealing statements in today’s opinion is the Court’s grim warning that the criminalization of homosexual conduct is “an invitation to subject homosexual persons to discrimination both in the public and in the private spheres.”

[…] At the end of its opinion–after having laid waste the foundations of our rational-basis jurisprudence–the Court says that the present case “does not involve whether the government must give formal recognition to any relationship that homosexual persons seek to enter.” Ante, at 17. Do not believe it. More illuminating than this bald, unreasoned disclaimer is the progression of thought displayed by an earlier passage in the Court’s opinion, which notes the constitutional protections afforded to “personal decisions relating to marriage, procreation, contraception, family relationships, child rearing, and education,” and then declares that “[p]ersons in a homosexual relationship may seek autonomy for these purposes, just as heterosexual persons do.” Ante, at 13 (emphasis added). Today’s opinion dismantles the structure of constitutional law that has permitted a distinction to be made between heterosexual and homosexual unions, insofar as formal recognition in marriage is concerned. If moral disapprobation of homosexual conduct is “no legitimate state interest” for purposes of proscribing that conduct, ante, at 18; and if, as the Court coos (casting aside all pretense of neutrality), “[w]hen sexuality finds overt expression in intimate conduct with another person, the conduct can be but one element in a personal bond that is more enduring,” ante, at 6; what justification could there possibly be for denying the benefits of marriage to homosexual couples exercising “[t]he liberty protected by the Constitution,” ibid.? Surely not the encouragement of procreation, since the sterile and the elderly are allowed to marry. This case “does not involve” the issue of homosexual marriage only if one entertains the belief that principle and logic have nothing to do with the decisions of this Court. Many will hope that, as the Court comfortingly assures us, this is so.
Full horrifying opinion here, where he says he’s got nothing against the gays, he just thinks they’re going to hell.
