Taylor Marshall suggests a defense of marriage based on defending "matrimony":
Imagine someone at a cocktail party asks you, "Are you in favor in marriage equality?" What do you say? Are you against equality?!It's like the question, "Have you stopped beating your wife?" There is no satisfactory way to answer that question.Okay, so here's what you do in that situation. Change the word. Go with matrimony.Matrimony comes from the Latin matrimonium. It is a compound of two words: mater meaning "mother" and the suffix monium signifying "action, state, or condition."Matrimony refers to the conception of babies in the mother's womb. The very word refers to the primary use of holy matrimony.We must stress that matrimony is an institution for having babies. Traditionally, the ceremony for matrimony symbolized and focused on this reality.As matrimony became sterile through a contraceptive mentality over the last 50 years, homosexual unions (100% biologically sterile) became fully acceptable.So stress matrimony. Use that word and explain to people what it means. Matrimony entails motherhood!
