The whole article is complete BS.

Just one small example:

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.
