Once again, Wondering, you miss the point.Marriage regulations and requirements are determined by the states. They list these requirements in their general laws, some , most, define marriage as between a man and a woman in their constitutions. The regulations and requirements apply to all persons in their jurisdictions making them equal for each of them.
The states are beholden by the federal constitution to provide all persons within their jurisdiction equal protection of the laws. If they wish to exclude a class of persons, they must illustrate that doing so serves a legitimate state interest.
Have you ever noticed how you consistently fail to be able to indicate ANY such interest served by denying same sex couples equal protection of the law to marry? That's because your argument lacks any rational or factual foundation, it is based on nothing more than your own bigoted opinion.
