“Given that those that WROTE the Constitution believed homosexuality was a crime, it can safely be stated gay marriage isn’t a right.” Not just that, but not even a marriage. It is a civil union not a marriage.
In fact it was a seriously punished crime, usually execution. Jefferson changed the state of Virginia penalty for homosexual acts into merely castration and, IIRC, banishment.
