Oh, it's been going on since Cato ended his every oration to the Roman Senate with "Carthago delenda est."

I've never been able to follow the logic behind the argument that allowing same-sex marriage somehow cheapens or weakens heterosexual marriage. If a man is married to his wife, and his next-door-neighbor marries his male partner, how does the existence of the second marriage cheapen the first? How does it diminish the rights, privileges, and responsibilities of the first marriage?
