Gender is inseparable from sexuality. You cannot define sexuality without invoking gender. This is obvious, yet you continue to pretend that it's not the issue and you offer no logic otherwise.
Equal protection applies to both genders and as we've clearly demonstrated the genders were being discriminated against in bans on same sex marriage. One gender cannot marry a woman and one gender can. That's discrimination. It was clearly discrimination when one race could marry a white person when one race couldn't.
In 1996, the Equal Protection clause was extended to include gender. It was an 8-1 decision and guess who was the dissent? ******* Scalia, otherwise known as the intellectual center of the Supreme Court. His dissent he wrote: More specifically, it is my view that "when a practice not expressly prohibited by the text of the Bill of Rights bears the endorsement of a long tradition of open, widespread, and unchallenged use that dates back to the beginning of the Republic, we have no proper basis for striking it down."
Tell me that mother ****** wouldn't have voted to maintain interracial marriage bans if he had been on the court in 1967. After all, the ban on interracial marriage is not "expressly prohibited" and is a tradition that dated back to the beginning of the Republic.
