Well, if they're going to go with the "two consenting adults" argument, I guess they'll have to issue marriage licenses to incestuous couples. Father & adult daughter want to get hitched? No problem! Twin gay brothers--no problem! Brother & sister want to "keep it in the family"? No problem? Mother & son--make being "Mama's special boy" an official union.

Why not? If both parties are consenting adults, and traditional morality doesn't apply anymore, they shouldn't have a problem with it.

They can avoid estate taxes this way, since giving to the surviving spouse has an unlimited exemption.
