I'm still not quite over the most disgusting part of the Juan Williams spectacle yesterday:  watching the very same people (on the Right and in the media) who remained silent about or vocally cheered on the viewpoint-based firings of Octavia Nasr, Helen Thomas, Rick Sanchez, Eason Jordan, Peter Arnett, Phil Donahue, Ashleigh Banfield, Bill Maher, Ward Churchill, Chas Freeman, Van Jones and so many others, spend all day yesterday wrapping themselves in the flag of "free expression!!!" and screeching about the perils and evils of firing journalists for expressing certain viewpoints.  Even for someone who expects huge doses of principle-free hypocrisy -- as I do -- that behavior is really something to behold.  And anyone doubting that there is a double standard when it comes to anti-Muslim speech should just compare the wailing backlash from most quarters over Williams' firing to the muted acquiescence or widespread approval of those other firings.

But there's one point from all of this I really want to highlight.  The principal reason the Williams firing resonated so much and provoked so much fury is because it threatens the preservation of one of the most important American mythologies:  that Muslims are a Serious Threat to America and Americans.
