I think, as a Jewish person, people have generally been good at refuting genuine antisemitism, and most people have been very good at not conflating Jews in general with the Israeli government.
The rise in antisemitism is deeply unpleasant, but to me it feels like it's being conflated inaccurately with the Third Reich or something when clearly there is no threat of us being systematically oppressed by the government or indeed any political force that has a chance of being in government for the foreseeable future.
I personally oppose the Israeli government's treatment of the Palestinian people and particularly deplore the outright cruelty they are displaying through, for example the witholding of aid. I cannot possibly see any need for that other than cruelty and some twisted sense of payback (yes, I know it's a conflict, but this sort of action is specifically proscribed as a war crime), nor does anything Israel's forces are doing seem to be aiding in the return of hostages. They've brought back a handful, they've killed three - the only time numbers have been released is during a ceasefire brokered by a third party. Which tells you something. This is why I marched on Saturday with the Palestine demo Jewish bloc.
But at the same time I am not saying I'm The Right Kind of Jew and pro-Israel Jews are The Wrong Kind - although I don't feel quite the same way about Israel I understand many Jews feel they have to stand with Israel, because if they don't, who will? And they feel very strongly it's their only refuge if The Worst Happens -personally I have always felt the UK is safer for me in my family, but that's not the case for everyone as people need to understand that even though we 'seem to be doing alright' these days, we do have millennia of exclusion behind us, and that's a powerful anxiety.
