As If Our Marriages Do Not Exist

One thing that struck me about the DOJ's argument that DOMA does not violate the equal protection clause since homosexuals are still able to marry people of the opposite sex, is that this ignores the existence of same-sex marriage on the state level. If two women get married in Iowa, they can no longer enter into opposite-sex marriages, even though they still don't have federal recognition.

So right now, there exist a specific class of people (those who are married to a person of the same sex) who are totally excluded from federal marriage benefits.
