I do not know who is responsible for this poster plastered up in Jerusalem, whether this group or that one or another, and I presume some had proper intentions, to a certain extent, [Correction: i now do know. Here.] but what I highlighted
The authors do not know what they write.

Is this incitement?
A prejudicial statement? Collective besmirchment?
A political/ideological prouncement of agit/prop?
It isn't in the Jewish tradition.
