The post-shooting debate over political civility is cooling down, but passions are still raging over Sarah Palin’s claim that critics were guilty of perpetuating a “blood libel” against her. Palin’s initial use of the term, in a Jan. 12 video message, drew sharp rebukes from liberal, Jewish groups and even some conservatives. Since then, however, several Jewish notables, including Harvard Law professor Alan Dershowitz, Rabbi Shmuley Boteach and former New York Mayor Ed Koch have defended Palin’s use of the term. Palin weighed in again Monday during an interview on Fox News -- her first since the Jan. 8 shooting in Tucson of U.S. Rep. Gabrielle Giffords (D-Ariz.) that also left six dead and another 12 wounded. Palin defended her use of the term “blood libel” and said she understands its meaning.
