I agree. He's been very clear, convincing, and consistent in his argument against gay marriage. Any time a caller challenges him on the issue, he just drags out the same old proven arguments and lets us listen to them try to dodge, change the argument, name-call, etc. Anything to avoid answering the question. Beyond that, his show in general is the best out there, I think. I can't imagine Limbaugh, (though I like his show), having "disagreement day" where he only allows callers who disagree with him to call in and challenge him.
Actually, the only time Medved takes a call that agrees with him, is when he has on a guest from the left. He makes mincemeat out of every caller. He's much tougher than Rush.
