@ErikUden Since it is this time of the islamic year again and Berlin having quite a history with antisemitic groups staging (often illegal) assemblies there, I would prefer to wait for the big picture and more information.

Generally, if somebodies solution to the old conflict is eradicating all jews, his ideas have not travelled far since Amin al-Husseini. If this also involves putting palestine under Hamas/Iranian rule, much worse.
