Set aside some utopian conception of what marriage is or should be about in the ideal, and instead recognize the way we live now — how and why we marry and how children are brought into this world and the homes in which they are raised. There are hundreds of thousands of children alive today who stand to benefit from being raised in more-stable, two-parent households. Every state allows gay people to raise children — and nearly all allow homosexuals to adopt or serve as foster parents. If this is acceptable (and few would argue that it’s worse for a child to be raised by gay parents than no parents at all) how can it be in the interests of these same children to ensure that they are raised in less optimal conditions? So even if one accepts the premise that protecting children could be a legitimate basis for refusing to recognize same-sex marriage, it is hard to make the practical case — at least if one is genuinely motivated by the interests of children.
Does any of this matter? As a legal matter, perhaps not. If the Supreme Court acts as expected, these issues will be moot. But perhaps if conservatives think more about the children, they will feel a little better about the practical implications of such a result.
