As a general rule, I would contend that if something is morally wrong, then it should be possible to present non-fallacious and reasonable arguments to show that it is wrong. I would also probably add that there should be actual facts involved. I would obviously not claim that the arguments must be decisive—one generally does not see that in ethics. While people continue to argue against same sex marriage, the arguments continue to be the usual mix of fallacies and poor reasoning. There is also the usual employment of “facts” that are often simply not true.
In the United States, the latest battle over same-sex marriage is taking place in Utah. The state is being sued on the grounds that the amendment that forbids same-sex marriage is a violation of their rights. The lawsuit certainly has merit—a state does not get to violate constitutional rights even if many people vote in favor of doing so. As such, a rather important legal question is whether or not same-sex couples’ rights are violated by this law.
Utah is following the usual model of arguing against same-sex marriage, although they have at least not broken out the argument that allowing same-sex marriage will lead to or is equivalent to a person marrying a goat.
As might be expected, they made used of the usual pair of fallacies: appeal to tradition and appeal to common practice by claiming that defining marriage as being between a man and a woman is correct because it is “age-old and still predominant.”
Utah also tried the stock procreation gambit, with an added bit about the state’s interest: “Same-sex couples, who cannot procreate, do not promote the state’s interests in responsible procreation (regardless of whether they harm it).” Utah has also made use of the boilerplate argument about “responsible procreation” and “optimal mode of child rearing.”
Same-sex marriage is thus criticized on two grounds in regards to “responsible procreation.” The first is that same-sex couples cannot procreate naturally. The second is that same-sex couples will fail to provide an “optimal mode of child rearing.” To deny same-sex couples the right to marry because of these criticisms would require accepting two general principles: 1) marriage is to be denied to those who do cannot or do not procreate and 2) people who are not capable of the “optimal mode of child rearing” are to be denied marriage.
The first principle entails that straight couples who do not want children or cannot have them must also be denied marriage. After all, if an inability (or unwillingness) warrants denying same-sex couples the right to marry, the same would also apply to different-sex couples.
This principle would also seem to imply that couples who use artificial means to reproduce (such as in vitro fertilization or a surrogate) must be denied marriage. After all, same-sex couples can use these methods to procreate. Alternatively, if different-sex couples can use these methods and be allowed to marry, then same-sex couples who procreate would thus also be entitled to marriage.
The principle would also seem to entail that all married couples would be required to have at least one child, presumably within a specific time frame to ensure that the couple is not just faking their desire (or ability) to have children in order to get married. This would certainly seem to be a violation of the rights of the parents and a rather serious intrusion of the state.
The second principle would entail that straight couples who are not optimal parents must be denied marriage. This would seem to require that the state monitor all marriages to determine that the parents are providing an optimal mode of child rearing and that it be empowered to revoke marriage licenses (much like the state can revoke a driver’s license for driving violations) for non-optimal parents. Different-sex parents can obviously provide non-optimal modes. After all, child abuse and neglect are committed by different-sex couples.
While I do agree that irresponsible people should not have children and that the state has an obligation to protect children from harm, it seems absurd to deny such people the right to marry. After all, not allowing them to marry (or dissolving the marriage when they proved irresponsible) would hardly make such people more responsible or benefit the children. Now to the matter of the state’s interest.
For the sake of the argument, I will grant that the state has an interest in having people reproduce. After all, the state is just a collection of people, so if there are no new people, the state will cease to exist. Of course, this also would seem to give the state an interest in immigration—that would also replace lost people.
This interest in procreation does not, however, entail that the state thus has an interest in preventing same sex-marriage. Allowing same-sex marriage does not reduce the number of different-sex marriages—that is, there is not a limited number of allowed marriages that same-sex couples could “use up.” Also, even if there were a limited number of allowed marriages, same-sex couples would only be a small percentage of the marriages and, obviously enough, marriage is not a necessary condition for procreation nor responsible procreation. That is, people can impregnate or be impregnated without being married. People can also be good parents without being married.
In light of these arguments, the procreation argument against same-sex marriage is still clearly absurd.
