I was just going through my files and found this letter to the editor I wrote about a year ago. It was never published. I'll translate it into English below:

Es ist schon ein genialer Schachzug, in dem Moment, wo es um Moral und Ethik geht, die Kinder im Namen der Integration nach der Konfession ihrer Eltern zu trennen. Ich schlage vor, nach dem gleichen Muster in anderen wichtigen, integrationsrelevanten Fächern zu verfahren. Wie wäre es mit parteigebundener, also sozialdemokratischer und hristdemokraticher, Gemeinschaftskunde? Die Kinder liberaler, grüner, bibeltreuer, republikanischer, nationaler und linker Eltern hätten frei. Kinder von Eltern ohne Stimmrecht könnten zweimal die Woche in Mitbürgerkunde unterrichtet werden.

Translation:

It is a brilliant move to separate kids according to the religious beliefs of their parents at the very moment when the subject matter is ethics and morals and to do so in the name of integration. I propose approaching other subjects which are relevant to integration the same way. How about having civics taught according to the party affiliation of children's parents - social democratic and Christian democratic civics classes? The children of liberals, greens, Bible-party, republican, nationalist and leftist parents could have study hall for an hour. The children of non-citizens could have two hours per week of instruction in "Mitbürger-studies" ("Mitbürger" is a German word meant to sound inclusive, but has in recent decades come to imply those who are among us as citizens, but not really citizens, not really part of the community).
