I'm late to the party on Rick Santorum's comments on the right to privacy and homosexuality. There's good commentary from Glenn Reynolds, Eugene Volokh, Virginia Postrel, Chris Lawrence, Kevin Drum, John Scalzi, Jonah Goldberg, and Andrew Sullivan. Jacob Levy has posted an awesome collection of links as well.

Having read the entire interview -- you should too -- I do tend to agree with Eugene Volokh that Santorum has a leg to stand on in regard to his legal arguments. Nevertheless, the following seems clear to me:

1) Santorum thinks that the public acceptance of homosexuality is destroying our country's moral fiber
2) Santorum equates homosexuality with other activities -- polygamy, adultery, sodomy, or "man on dog" -- that he believes is destroying our country's moral fiber.
3) Santorum's lack of faith in Americans' ability to stick to their respective faiths is pretty appalling -- although, as Virginia Postrel points out, perfectly consistent with certain strands of conservative thought.
4) Santorum was not duped into this conversation -- he knew what he was saying.
5) That's one freaked-out AP reporter

UPDATE: Via Sullivan, I found this CNN transcript. Tony Blankley's comments on this are worth repeating:

I disagree with almost everything he [Santorum] said, both his legal analysis, which is -- I don't think it's sustainable. I'm confident the Supreme Court can distinguish between consensual conduct by gays and lesbians in private and incest, which is not consensual, by definition of the relationship.

So I don't buy his argument. I don't buy his argument that American families are in danger from the 1 percent to 2 percent of homosexuals in the country. We've had that population since the beginning of time, and American families are fine.

However, I'm in the minority, not just in the Republican party, in the Democrat party, amongst independents, in the country, in the world, that he sits and heard him say that the standard Catholic position. I disagree with it. I'm not a Catholic, but that is the received position of the vast majority of mankind. I wish it weren't, but that's the position.

That's a pretty good summary of what Alan Wolfe's research says on the topic as well.
