The piece ends with more arguments against segregated and religious schools, where he asks whether liberal or fundie Islam would be taught; and an extended argument against voluntary integration programmes (in particular when husbands could keep wives at home).

He again cites examples from 20 years ago which I can't check back on, nor can I check whether Dutch law at the time regulated religious schools in any way. At any rate, Mohammed Bouyeri, the murderer of Theo van Gogh, did not come from segregated schools, and went bonkers in religious matters at age 25 after he turned a dropout and then his mother died, according to Wikipedia.
