Abstract
Most men engaging in homosexual sex have been socially construed as pariahs for much of human history, and women engaging in such sex in the modern age are subject to similar social disapproval. Same-sex marriage has, therefore, been similarly disapproved, and there are several arguments offered in objection to it. The thesis of this essay is that those arguments are not rationally probative and that they are, in fact, cloaks to hide the emotion of revulsion toward homosexual sex. We consider that emotion of revulsion, neuroscientific data related to it, and the arguments of the Catholic Church against homosexual acts, and conclude that those arguments arise, at least in part, from that emotion of revulsion and are not rationally probative.
