The headscarf is more than just a piece of fabric, more than just another article of clothing, and definitely not some hip lifestyle accessory that heavily made-up girls should use to add a little color to their wardrobe. No, the head scarf is a "flag and symbol of Islamists" which "followed a crusade all the way to the heart of Europe by the 1980s." Or so says iconic German feminist Alice Schwarzer in her new book, "The Great Cover Up: For Integration, against Islamism".

The book was recently published in German under the name "Die grosse Verschleierung: Fuer Integration, gegen Islamismus," and its strong statements been an injection of yet more fuel into the already burning integration debate in Germany.

Teachers are no longer allowed to wear the head scarf in German public schools, and now Schwarzer has demanded the next step: Girls should be forbidden to wear it as well.

"Only this forceful act would finally give the young woman from a fundamentalist orthodox family the chance to move with freedom and equality, at least within the confines of the schoolyard," Schwarzer writes.

Many readers are likely to react negatively to this demand for a headscarf ban. In themselves, bans clash with freedoms and rights that are supposed to be self-evident in Germany: the right to individual self-determination, the freedom of religion.
