I think it’s really difficult for kids to be in an environment where the majority of your peers see the ethnonationalist state for your co-religionists killing tens of thousands of people soo brutally in response to a brutal attack that affected a small fraction of that number. The reactions of the schoolmates presumably run through a spectrum from bored indifference to outright antisemitism. The only specific allegations of actual antisemitic actions arise in relation to a couple of incidents in an Educate together non denominational school, but this probably is a fluke of geography.
The Jewish chronicle has changed in character from a good newspaper to a sinister propaganda rag.
But I think that Maurice Cohen’s concerns should be carefully considered. There should be a clear pathway to investigate a credible claim of this nature, probably via the Human Rights and Equality commissioner and such a pathway doesn’t seem to exist in the no man’s land between equal status acts and incitement to hatred. But maybe there is such a pathway but it’s not widely known?
