"Journalists and pundits should not manufacture a blood libel that serves only to incite the very hatred and violence they purport to condemn."

===================================================
Blood libel (also blood accusation[1][2]) refers to a false accusation or claim[3][4][5] that religious minorities, usually Jews, murder children to use their blood in certain aspects of their religious rituals and holidays.[1][2][6] Historically, these claims have–alongside those of well poisoning and host desecration–been a major theme in European persecution of Jews.[4]
