Is This Thinking? Is This Relevant?

I am engaged in a discussion with Marshall Art over the alleged strengths and weaknesses of an article at an on-line magazine called American Thinker. The article in question attempts to argue that "all liberals are appeasers". After it is pointed out this is demonstrably untrue, Marshall flails around. I pointed out that the piece in question is poorly written, but Marshall wants to know what I think of the "argument". I hand this one off to all of you, dear readers. I would like your opinions, which may differ from mine (which you can read in the comments).
