That Sarah sure does have a way with words. Palin’s latest, not an “oops” moment but actually something she posted online, upped the righteous hackles of a lot of people and left others going, “huh?” So, what is it? In short: “blood libel” is an accusation originally and historically used as a means of inciting hatred against Jews. (Reminder: Palin has worked hard to be sure that no one doubts her evangelical Christian identity.) It has evolved to include anyone falsely accused, which is how Palin appears to have intended it when she claimed to be the victim of a blood libel following allegations that her rhetoric and politics contributed to Loughner’s twisted decision to shoot in Tucson.
