Many of Brad DeLong's commenters are unable (or simply being willfully obtuse) to understand his "alternative universe" post in which Scalia mocks his fellow justices for their Loving v. Virginia decision, which nullified miscegenation laws way back in 1967.
Brad's point, obviously, is that the legal principles that Scalia appeals to in order to mock the recent sodomy case would apply equally to Loving v. Virginia, and likely Brown v. Board of education and Dred Scott as well, at least according to this non-lawyer.
Conservatives rarely pipe up and say what they think about those decisions these days...
