Because a few moments of googling for ME turned up the following links, which certainly suggest that the climate in France is certainly not particularly warm to Jewish people and moderate Muslims:
Ah, but that wasn't the assertion, was it? In case you're unable to scroll back to the comment to which I was replying, here's the statement:
I was just reading that, due to Muslim students, it's no longer possible for someone to be a teacher in France while being openly Jewish.
No. Longer. Possible. For someone to be a teacher in France while being openly Jewish.
Shall we take a little walk over to a few French universities and examine the names teaching Humanities? Political Science? Medicine? You want to make a little bet on whether or not it is "possible for someone to be a teacher in France while being openly Jewish"?
France is home to the world's third largest Jewish population. Not Europe's third largest, but the world's third largest. Let me guess: you think they're all money-lenders and pawn brokers? There are three quarters of a million Jews in France and 600,000 of them are French citizens. You believe none of them are teachers?
Yes there is anti-semitism in France. And the anti-semitism that is on the rise is as much from the conservatives and nationalists in Europe as from muslims. If you want to see anti-semitism, you can't do much better than white guys with SS tattoos on their necks and shaved heads. And make no mistake, there are neo-Nazis, the white Christian kind, on the rise all over Western and Northern Europe. This is not a new development, since I seem to recall some dustup in that region in the middle part of the last century. And long before that. But when you make a statement about whether it is "possible" to be a Jewish teacher in France, based on some right-wing blog or Breitbart or something, you should always use your head for a minute before accepting it as gospel.
