Rush is clearly against judges going against the will of the people. Recently in Arizona, and CA. That is where he is. My point is he doesn’t see gay marriage as fake.
He may not have commented the way you wanted, but he has come out against it many times. He has always focused on the legal aspects of the issue, that is just his mode. Because someone doesn't put something the way you want or give it the specific attention you want, doesn't mean they disagree.
