Marriage between same sex couples in the united states is a fact.Marriage is simply the union of a man and a woman, this is a fact! No allowance has been made for any other combination. Now if you want to have a social contract or legalized relationship rights of some sort via the courts and have the government accept it from the standpoint of taxes, benefits, etc. That would be quite a different thing and would likely be supported by a large number of the population.
Not an opinion... a fact
