There is a difference between not wanting to learn English and asking allah to destroy the homosexuals, Jews and Americans.
There also is a difference between what people believe and what is real. The fact is that the they import extremists imams and thereby stop the integration proces. Instead of fitting in, there are much more fundamentalists amongst the youths now, notebly the Moroccan youths.
The schoolbooks for islamic schoold published by the foundation al-Waqf contain references that homosexuals, Jews and westerns are lower than pigs and dogs. Also there is called for the kids to later fight people until they convert to islam.
Did these Italian and Greek schoolbooks teached that too?
Of course not, because Italian and Greek immigrants all went to the same public schools, where (in the early 20th century, at least) they read *patriotic* American textbooks & literature. In English.
