Ever since and before the Supreme Court Proposition 8 and DOMA decisions a number of our, shall Eli say, states where only mouth breathing is allowed, have been screaming that they will never accept gay folk marrying each other. Since there are another number of states where gay folk can marry each other the mouth breathers are pledging to never accept a marriage certificate for a gay couple from states where gay marriage is allowed.
Eli has a modest suggestion motivated by recent Supreme Court decisions emphasizing the rights of states, simply that states which acknowledge gay marriages should reject ALL marriage licenses from states that don't. Married in VA and living in MD? Sorry, you are not married in MD. As they say, sharpening the contradictions.
Should be fun.
