The words "There is no excuse for savagery" can equally be used in response to what the IDF has done to ordinary civilians in Gaza and the West Bank. NONE of what the IDF is doing can be called "self defence" any longer and there is no "existential crisis".
All there is is a nationalist movement which has lost its humanity and degenerated into nothing more than an obsession with crushing people for the sake of crushing people, taking land just because they can take land.
None of this protects anybody against antisemitism, and you know it.
