The left has its share of wackos, but the right has -- and takes very, very seriously -- people like Robert George, who defends Rick Santorum's recent remarks on sexual matters in this National Review Online piece.
The problem with George isn't that he thinks that a Supreme Court endorsement of an absolute right to privacy would be open the door to legalization of consensual adult incest and other rare but nasty behaviors -- you can find centrists who've argued the same thing. No, the problem with George is that he considers any sexual act apart from intercourse to be "intrinsically non-marital" -- even if it takes place between a husband and wife. To George, the things lawfully wedded spouses do that aren't intercourse are “sexual misconduct,” “illicit sex acts,” and “immoral sex acts.” It's entirely likely that Senator Santorum agrees.
You know, maybe we should spend a little less time wondering about what might happen if there's an expansion of the right to privacy -- and a little more time wondering what the limits on our private behavior would be if people like Robert George and Rick Santorum had their way.
