Halpern provides numerous citations about the increasing use of this gesture, from England and France to Holocaust era camps in eastern Europe and Israel. He provides a Youtube video as evidence.

France is considering banning all of Dieudonne's performances. Under French law it is illegal to disseminate hatred. The salute began in 2009, when Dieudonne was running for the European Parliament as head of the anti-Zionist party. The quenelle [reverse Nazi salute] became his symbol.What a coincidence that a Nazi sympathizer happens to be anti-Zionist.

In case you're wondering, no, Israel is not mentioned once in the article.
