The underlying issue at hand is a battle between proponents of natural law and proponents of legal positivism. I’ll probably botch this explanation up.
Natural law proponents see the world has having an inherent order that existed before and without the state. An example of this is the Declaration of Indepence, wherein Thomas Jefferson wrote, “We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights…”.
Legal Positivist feel that the law is the only source of right and wrong. Nazi war criminals tried to use this rational at the Nuremberg trials. They said that because they were following the orders of the lawful and popularlly supported government of Germany, that they could not be convicted of crimes. That other states could not impose an alien morality upon them. (BTW, this defense did not work, and most of them were executed.)
Since the traditional husband-wife family existed before the state, a natural law proponent would hold that the state should continue the institution that is the basis of our society.
The legal positivist sees marriage as a legal contract between two parties which confers upon them special benefits from the government. Thus, whether the individuals involved are a man and woman, a man and man, or a woman and woman, it doesn’t really matter.
As far as my opinion on the constitutionally amendment:
I would give deference to the states as to define what is a marriage. In my state, I would not support marriage between anyone but a man and a woman.
But, because of the full faith and credit clause I don’t support a constitutional amendment. An amendment that allows the individual states to not accept the marriages that are not legal within their own states.
I would probably support the broader amendment as well if it looked like it might actually make it through the process with more ease. An amendment that would define marriage as between a man and a woman. Only because amendments are very hard to pass, and if this looked like it might pass, the chances of it failing and the amendment I prefer suceeding, would be very low.
Article IV Section 1 of the United States Constitution: “Full faith and credit shall be given in each state to the public acts, records, and judicial proceedings of every other state. And the Congress may by general laws prescribe the manner in which such acts, records, and proceedings shall be proved, and the effect thereof.”
BTW, I am not a fundy or a Republican. But, I probably will vote for President Bush in the next election but not because of the gay marriage issue.
