Because, well, that would be too unpleasant for the public being made to do the broadcaster’s forced funding to have to face.
Germany’s state-run television channel ARD recently decided not to air a documentary it had itself commissioned concerning the latest outbreak of antisemitism in Europe and the Middle East because the people doing the film apparently did this job much too well (after enough noise was made about this decision the ARD had to broadcast it anyway).
This could trouble viewers in a country where at least 40% of its citizens hold anti-Israel, antisemitic views. Or so the reasoning must be. ARD documentaries propagating negative views about Israel get aired here all the time, however. This having to do with balanced journalism or something. Or so the reasoning must be.
Anti-Zionism is not a legitimate political position, but rather a movement against the Jewish and democratic state. It is Antisemitism 2.0.
PS: Meanwhile… The latest boycott Israel campaign from BDS seems to be making great strides forward here in Berlin. It is unclear at this point whether the ARD will be commissioning a documentary about this campaign or not.
