Another laughable piece from Saunders. Anti-Semitism among native Europeans has never disappeared, although in the recent years it is mostly manifested by left's obsession with Israel and Zionists.
But even with this endemic hostility, Jews were doing fine in Europe. The resurrection of  anti-Semitism as direct existential threat coincided with massive increase in Muslims in Europe.  Before that, old fashioned Antisemitism was relegated to cranks and their worst acts were desecrations of cemeteries or Holocaust denial.
The Islamic variety on the other hand brought direct threat to personal security.  And ISIS terror is not the only source.. Muslims are so hostile to the Jews, that public wearing of Jewish symbols is highly discouraged unless one wants to risk harassment and battery.  If Saunders wants to find truth the simplest test would be to ask French Jews who came to Israel why they did it.  I am sure that very few (if any) will list  National Front as the reason.
