There have been plenty of reports debunking the Obama Muslim allegation, but not enough about the racial subtext of "smearing" a politician for being Muslim.

Fairness & Accuracy in Reporting released a report documenting the 12 Islamophobes in US media. The all-star list includes (unsurprisingly): Bill O'Reilly, David Horowitz, Michelle Malkin, and Sean Hannity.

FAIR's senior analyst Steve Rendall told Brooke Gladstone on On The Media:

If someone was accused of being a secret Jew we'd have a discussion not only about the fact of the matter, but one about anti-Semitism in the campaign. The second part is not happening in this case.

How do these viral e-mail rumors get started? The Nation's Chris Hayes had an excellent piece last year about the origins of these smear campaigns.
