With its decision in 2015 to allow Muslim teachers to wear headscarves in schools, the Federal Constitutional Court did not exactly help to defuse an issue of contention.

You can see that now in the Berlin case.

The neutrality law prescribes abstinence in school service for all religious denominations.

The rules in the judiciary are similar and, if in doubt, even stricter.

Berlin did not want to follow the Federal Labor Court, which considered the school practice to be unconstitutional, and lodged an objection in Karlsruhe.

But Karlsruhe rejected him.

The Berlin neutrality law must therefore be changed.

Criticism of the headscarf is racist?

The reactions from the Berlin Senate suggest that the headscarf is less about religion and more about beliefs.

The justice senator from the Left Party welcomed the nullity of the neutrality law with the words that "attributions with racist connotations" would come to an end.

This probably means that it is racist when the headscarf is criticized as a sign of patronizing Muslim women and that in turn as a deviation from the culture cultivated in Germany.

You have to look the other way to believe that the teachers' headscarves acted as a sign of a religion and not of a certain attitude towards the students.

That the political left in Germany sees progress in this is as big a mystery as the wind blows from Karlsruhe.
