The gesture, however, is "in danger of being mistaken" for the same but indistinguishable "wolf salute" used by right-wing extremists, according to Bremen officials.
When Turkish national football player Merih Demiral used the salute to celebrate scoring a goal in Turkey's round of 16 match against Austria earlier this month, it became the centre of a diplomatic and sports controversy.
Interior Minister Nancy Faeser called it "completely unacceptable" that "to use the football championships as a platform for racism" was still allowed in Germany, despite the sign not being outlawed as it is in neighbouring Austria and France.
The European football governing body Uefa suspended Demiral for two matches following the summons of the ambassadors of Germany and Turkey to Berlin and Ankara, respectively.
Protests over his ban sparked calls among Turkish fans to use the symbol even more to show their anger at what Turkish President Recep Tayyip Erdoğan called an "unfair and biased" reaction. "Does anybody ask why the German national jersey has an eagle, or the French jersey a rooster?" he questioned reporters before Turkey's quarter-final match against the Netherlands in Berlin.
Erdoğan said that Demiral had just made the gesture to express his delight and that the ban was politically motivated.
Germany hosts around 3 million ethnic Turks, making them the largest ethnic minority in the country and the biggest Turkish diaspora worldwide.
Patricia Brandt, a spokesperson for Bremen's education authority, stated that discussions about the silent fox gesture and the possibility of banning it had been ongoing for a long time, but the city felt it had no other option at this point.
Comment: Surely there are more pressing issues in Bremen?
"The political meaning of the hand gesture is absolutely incompatible with the values of the city of Bremen," she said.
But she noted that more teachers now view the gesture as "pedagogically outdated" and find its "regulatory style" to be overly rigid and condescending.
I wonder how many ethnic Germans are in Turkey?
