So Jem, imagine you were going to argue the case against gay marriage before the Court. What argument would you use to convince the court that you or other heterosexual people could suffer substantive harm to your constitutional rights if gays were allowed to marry. I'm afraid harm to the figurative institution of marriage is not substantive. You'll have to go back to the drawing board on that one. And you'll also have to show that the substantive harm done to you, and many others, outweighs the substantive harm done to gay people by being denied the right to equal protection.
And while I'm at it, what on Earth does this have to do with Left or Right politics. You seem to try and force every issue, no matter how far from politics into a political mold. This is a purely constitutional issue. In spite of that ridiculous comment of Roberts. If you don't believe it, read the Majority Opinion! And the pleadings! . .
Is Dick Cheney your idea of a "lefty"? Is Laura Bush your idea of a "Lefty"' ? Hah! What an idiot you can be at times! Dick Cheney is further right than Josef Mengele, and twice as evil!!!
Here for your personal enjoyment is what's his names take (Oh, it's Stephen Colbert.):

[added in edit: In case you didn't realize it, Dickie and Laura are staunch supporters of Gays being able to marry. Hah, again!]
P.S. I know your a supporter of gays being able to marry, so don't blow your cover, and wreck our high opinion of you with nonsense comments. Take credit graciously for being on the "right" side of this issue.
