First, everyone should know that Saunders flunked out of York University in the 1980s.  He wasn't even smart enough to get a BA at York!  Second, Mounk's latest study has nothing to do with Europe's Jews.  Third, here is the link to Reynie's actual study: www.fondapol.org/wp-content/uploads/2015/03/Anti-Semitic-Attitudes-in-France-New-Insights-20151.pdf  
As one can see, Saunders has dramatically underplayed Muslim anti-Semitism, as he always does.  Muslim anti-Semitism is monstrous and deadly.  51% of French Muslims are anti-Semites, and that figure rises to 63%!!! among practicing Muslims.  The fact that Saunders advocates flooding Europe with Muslims knowing their murderous anti-Semitism shows that Saunders is an advocate of anti-Semitism himself.

This article is dangerous nonsense, as usual.
