[Y]ou cannot argue that the demonization of a religious and ethnic other for the purposes of justifying endless, limitless war is a bad thing and then apply the same blanket comparisons to your political opponents. Rather than "destroying the rotted premise" at the heart of the moral cretinism of the warmongers he is criticizing, Greenwald is reinforcing it by legitimizing its use in domestic political debate. This argument doesn't illuminate anything about the motivations of "The Enemy"; it makes the GOP as a whole "something utterly foreign, inhuman, and subject to entirely different drives than Us." I don't see where that gets anyone, particularly since I don't think it's accurate.
Save your eyes. Take breaks.
