...so you don't have to.
Here's a taste of what Hitch has to say:
Propagandistic writing of this kind can be even more boring than it is irritating. For example, Mamet writes in “The Secret Knowledge” that “the Israelis would like to live in peace within their borders; the Arabs would like to kill them all.” Whatever one’s opinion of that conflict may be, this (twice-made) claim of his abolishes any need to analyze or even discuss it. It has a long way to go before it can even be called simplistic.
[Mamet] shows himself tone-deaf to irony and unable to render a fair picture of what his opponents (and, sometimes, his preferred authorities, like Hayek) really believe. Quoting Deepak Chopra, of all people, as saying, “Our thinking and our behavior are always in anticipation of a response. It [sic] is therefore fear-based,” he seizes the chance to ask, “Is it too much to suggest that this quote contains the most basic prescription of liberalism, ‘Stop Thinking’?” On that evidence, yes, it would be a bit much.
