In my essay in the 1982 Supreme Court review, to which Professor Tollett refers, I did not say that the original purpose of the Reconstruction Amendments is probably no longer worth taking seriously. Instead, I said that the notion that the amendments are limited to race, and do not also apply elsewhere, is probably no longer worth taking seriously. The difference is not technical; these are entirely different propositions.
To say that the equal protection clause covers not simply race discrimination but also (for example) sex discrimination is to say something that fits with its broad text. It is not at all to deny that the fundamental purpose of the clause is to counteract the subordination of blacks. On this point, Professor Tollett and I are in basic agreement.
