Just like in medieval times the blood libel is used to incite attacks on the Jewish people. Remember the Al Dura hoax? The young child who was supposedly shot by Israeli forces? Mainstream media across the globe picked up the video of a father desperately trying to shield his son from Israeli gunfire and the boy being shot dead.

That video and its pictures helped incite the horrific homicide bombings of the second intifada. It was years later we learned that a Palestinian cameraman who worked for one of the French TV Networks staged the video. All along the French network had the full tape showing the boy and his father rehearsing their act. The mainstream media was all too quick to accept the blood libel story of the child-hating Israelis because it fit their narrative.

The Goldstone report is another example. According to this UN commissioned report, during the Gaza War of 2008 Israeli soldiers deliberately targeted Palestinian civilians. The report was well received by the UN, world leaders and even the President of the United States who began calling for an independent investigation. The problem with the report was that Goldstone only interviewed Hamas sources for details on specific incidents and refused to consider Israeli evidence proving the claims as lies. Even though Goldstone himself now disputes the report’s claims, much of the world still believes its libels as truth.

The blood libel is also part of the language of the progressive left.

Daily Kos, the largest progressive website/social community whose annual convention called Netroots Nation has been addressed by Secretary of State Clinton and her husband, Nancy Pelosi, Harry Reid and President Obama among others, makes it a habit of portraying Jews as blood-thirsty Nazis.

One political cartoon posted on the site shows a bloodstained Israeli flag with the "Jewish Star" morphed into a swastika. It still adorns a post called "Eulogy before the Inevitability of Self-Destruction: The Decline and Death of Israel," which warns of "A Zionist movement multiplying like cancer cells."
