I strongly agree. The double-standard is remarkable though. Merely questioning the liberal position with less than a perfect rhetorical command is nearly criminal, but if you endorse a liberal position, you can be incorrect and even downright hateful toward your position, and lots of respectable (sometimes powerful) people will defend you against any criticism. I always catch a lot of flak for calling out liberal advantages (I'm a moderate liberal, for whatever that's worth), but pretending they don't exist hasn't exactly been doing wonders for the tone of our political discourse either.
