This picture is blood libel.
It depicts Bibi, with a Jewish star, eating a small child.
Blood libels have their root in white Christian anti-Jewish propaganda of the Middle Ages, in which Jews were accused of draining Christian children’s blood for use in matzah on Passover. Which is ridiculous, because consuming blood is strictly forbidden in our religion and culture.
However, this ancient libel, never fully put to rest, has been given new life not just in Europe, but also the Middle East. Depictions of a Jew - any Jew, for any reason - imbibing blood recalls this libel, and has wider antisemitic implications long beyond the shadow of Israel-Palestine politics.
Like this image here, which appeared in the Independent some years back:
Maybe the intent was to depict Netanyahu as a horrible leader more interested in carnage than leadership. However, intent does not undo the wider context of blood libel and blood libelous images, nor undoes its damage to Jews worldwide, especially notable in this case because the Star of David on his forehead serves to implicate his Jewishness as the source of bloodthirstiness, rather than his own personal failures.
Don’t be a tool. Don’t use blood libels.
