This bit starts well but tails off into a contradiction of the IHRA definition (which isn’t mentioned once!) by stating “But holding all Jewish people in the UK responsible for the actions of Israel, or demanding they denounce Israel can be antisemitic.” According to IHRA it is.
You’ve framed the argument alright, no mention of defence from terror attacks or continued calls for Israel’s destruction. Odd for a organisation to make a training guide on antisemitism with such a biased stand against the Jewish State.
