"The idea driving "gay marriage" is the idea that "gay is like black" and that opposition to homosexual marriage is like opposition to interracial marriage. Intellectually, this is an utter misnomer. It's not discrimination to treat different things differently. Two men cannot fulfill the public purpose of marriage; indeed, their inclusion in the pool of married couples will undermine the very idea that marriage has a clear public purpose, rooted in the natural family and in the need for responsible procreation."
