"Shut up" is not an argument

Steven den Beste is heard once again, as cogent as ever:

I keep running into this from lefties. They criticize others (us), and if in turn they're criticized suddenly they squeal about "censorship!" and "McCarthyism!" Their freedom of speech demands that we not say anything in our own defense, let alone actually point out their problems.

And so it is here. Howard Fineman is deathly afraid that the Republicans will point out what the Democrats actually stand for. How dare those scheming Republicans actually defend themselves!
