From a very depressing story in the IHT: :
Anti-Semitism is so prevalent in some of the housing projects that ring Paris and other major French cities that “it’s become infused into the language,” according to Barbara Lefebvre, a history teacher at a French public school.
.
“Just about every week I see students in my class – where there are no Jews – insulting each other by saying, ‘Stop it, you Jew.’ Or ‘No, you can’t borrow my pen, it’s not yours, Jew.’ Or if their pen is broken they’ll say: ‘What’s wrong with my pen? It’s a Jew.’
.
“When you point it out, they say, ‘This is just a way of speaking.’”
