I think that's reading way too deep into something that's never really been challenged in court.I have addressed this several times in the past, but here it is again. There are certain states that allow first cousins to legally marry only if they cannot procreate with each other. They have to show proof that they are infertile or that the woman is over a certain age in order to be able to enter into a legal marriage. These are all recognized as legal marriages by the federal government. This alone shows that the federal government and at least some states cannot claim that procreation is the main state interest in marriage for them and that is why they are banning same sex marriage because they are legally saying the opposite for certain opposite sex couples.
