There is a crackdown/entrapment going on, and many people who took part in Pro-Palestinian demonstrations are then ID and catalogued. Palestinian flags on apartment windows and student dormitories are taken down by police. Not to mention, Palestinian flag that was painted in a shop's garage next to my house and has been there for literally 10 years, was painted over by the city government today. There is a concentrated effort to silence any Palestinian voice, and Germans are just as "clueless" like they were back in the 1940s.
Pro-Palestinian protests in many parts the country as well as Palestinian flags, pro-Palestinian speech and the Palestinian keffiyeh headdress have been banned with schools in Berlin given official permission to do so.
What happened is that schools CAN ban keffiyeh. And of course they can, political symbols of any kind always have been not allowed at schools. It was the same when I went 10 to 20 years ago.
