Am I missing something in your original comment? I don't see any comment regarding gay marriage anywhere up the tree.
I meant see my reply to the sibling comment of your comment, which raises the same point. Group rights and individual rights are not the same thing.
I truly don't see the difference in this case. You - as an individual - now have the right to legally marry whomever you choose provided they have the legal right to consent (e.g., old enough, of sound mind, etc.). You may not have any desire or need to exercise that right, but it's still yours all the same.
