What about people who are born with partially formed male genetalia, have a little surgery, and are then raised female. Would they be allowed to marry men under these new laws? What if they (as they often do) discover their medical history and switch their sexual identity back to being male. Would they then be allowed to marry women? I realize that this is a kind of silly question, but it reflects the real world that "defense of marriage" folks who want the world to be like fifties TV shows refuse to see.
