It was no surprise that the Supreme Court held Friday that there is a constitutional right to same-sex marriage. It is very difficult to distinguish the case from Loving v. Virginia, which in 1967 invalidated state laws forbidding miscegenation. There was, as an economist would say, a “demand” (though rather limited) for biracial marriage, and it was difficult, to say the least, to comprehend why such marriages should be prohibited. In fact the only “ground” for the prohibition was bigotry. The same is true with respect to same-sex marriage. No more than biracial marriage does gay marriage harm people who don’t have or want to have such a marriage. The prohibition of same-sex marriage harms a nontrivial number of American citizens because other Americans disapprove of it though unaffected by it.
