Marriage is simply the basis that society uses for simplicity of the family unit and continuance of the species. In a traditional marriage: Jane A. meets John B. Jane and John decide to live as one thus becoming Mr. and Mrs. John A. Jane and John have a child, Jack A. Jack A. meets Jill C. and so on. In a Gay Marriage: Jane A. meets Jane B. Jane A. and Jane B. decide to live as one thus becoming "Ms. and Ms. Jane ?" Jane A. and Jane B. can't produce children. Jane A. and Jane B. pass away. End of Story. If we as a society decide that marriage is only a means of co-habiting in a "civil union", regardless of sex, than it must decide that traditional marriage as we define it, and many of the laws involving it, need to be repealed, rewritten or no longer exist.
