Poorly, to put it briefly. This is why immigration-skeptic parties have cropped up and prospered across the continent. Why is it that so many Europeans think mass Islamic immigration is a bad idea? Incidents like this one in Paris:
Two Jewish brothers said they were abducted briefly and beaten by several men in suburban Paris in an incident that ended with one brother having his finger sawed off by an assailant. …
The kippah-wearing brothers, whose father is a Jewish leader in Bondy, were forced off the main road by another vehicle on to a side street, according to the BNVCA report. While the vehicle was in motion, the driver and a passenger shouted anti-Semitic slogans at the brothers that included “Dirty Jews, You’re going to die!” …
The vehicle forced the brothers to stop their car, and they were surrounded by several men whom they described as having a Middle Eastern appearance. The men came out of a hookah café on to the side street, according to the case report published by the news website JSSNews.
The alleged attackers surrounded the brothers, then kicked and punched them repeatedly while threatening that they would be murdered if they moved. One of the alleged attackers then sawed off the finger of one of the brothers.
Just don’t tell the Parisian tourism board.
Here in the U.S., there is an upsurge in anti-Semitic incidents, including coordinated telephone threats against Jewish organizations and desecration of Jewish cemeteries. Liberals try to pretend that these incidents are perpetrated wholly or in part by Trump supporters, notwithstanding the fact that Trump’s own family is partly Jewish. (Logic has never been a liberal strong point.) I would gently suggest that the problem lies principally elsewhere, and that Europe’s experience is instructive.
