Public Discourse has a good article on the relationship between same-sex marriage and the irrational judicial decisions made by judges formulating those decisions. Matthew J. Franck opens with the following statement:
One of the most striking features of the campaign for same-sex marriage has been the prominence of its assault on reasoning itself. The logical relations of legal categories with one another, as those categories represent persons, their interactions, and their rights and duties, are at the heart of all legal decision-making and ideally inform legislative and administrative policymaking as well. But the impulse to redefine marriage so that it is no longer understood as the conjugal union of a man and a woman has been consistently heedless of logic and the rational relations of legal categories.
Included in his analysis is that proponents of same-sex marriage do not offer a cogent definition of marriage; that they believe traditional marriage is simply a religious institution; and that same-sex marriage should be legalized in order to avoid hurting people’s feelings.
Franck offers some insightful analysis, and the rest of the article is worth your time. You can find it here.
