Detailed data on Muslim anti-Semitism in Western Europe is very limited. The few existing studies all point in one direction.
In 2011 Mark Elchardus, a Belgian sociologist, published a report on Dutch-language elementary schools in Brussels. He found that about 50 percent of Muslim students in second and third grade could be considered anti-Semites, versus 10% of others. It is logical to assume, in view of the age of these children, that their parents have imbued them with Jew-hatred.
In the same year Günther Jikeli published his findings from the 117 interviews he conducted with Muslim male youngsters (average age 19) in Berlin, Paris and London. The differences in attitudes between the cities were minor. The majority of the interviewees voiced some, or strong anti-Semitic feelings. They expressed them openly and often aggressively.
