A gay man can marry anyone that a straight man can. A gay woman can marry anyone that a stright woman can. So there is no discrimmination.

Be careful not to flop out the unsueable arguement of comparison of the old law against interacial marriage it will not work.

A balck man could not marry the same a a white man. Race was the basis of this discrimination.

Sex has always be a line accepted as a defining difference.
