The single truth in this debate that no one seems to point out is that marriage, as a social contract, is not between two people, it is between two people and everybody else. All the rights the individual above claims are rights not between the two married individuals, but rights of recogition required by the rest of society. This is why the 'private behavior' argument does not work-- this is demanding the recognition and accomodation, and therefore complicity, of everyone else. Any legislation or judicial edict instituting gay marriage is not to change the behavior of the couple in question, it is to change the behavior of everyone else in society.
BTTT!
