WHEN THE BBC invited me onto one of its talk shows recently to talk about the day's hot topic -- legalizing adult incest -- I thought of Rick Santorum.
Back in 2003, as the Supreme Court was preparing to rule in Lawrence v. Texas, a case challenging the constitutionality of laws criminalizing homosexual sodomy, then-Senator Santorum caught holy hell for warning that if the law were struck down, there would be no avoiding the slippery slope.
"If the Supreme Court says you have the right to consensual sex within your home," he told a reporter, "then you have the right to bigamy, you have the right to polygamy, you have the right to incest, you have the right to adultery. You have the right to anything."
It was a common-sensical observation, though you wouldn't have known it from the nail-spitting it triggered in some quarters. When the justices, voting 6-3, did in fact declare it unconstitutional for any state to punish consensual gay sex, the dissenters echoed Santorum's point. "State laws against bigamy, same-sex marriage, adult incest, prostitution, masturbation, adultery, fornication, bestiality, and obscenity are . . . called into question by today's decision," Justice Antonin Scalia wrote for the minority. Now, Time magazine acknowledges: "It turns out the critics were right."
