"
British Jews have raised concerns about increased vandalism at synagogues and
antisemitic comments online and in person, latterly due to the
Gaza war"
Manchester synagogue attack carried out by an radical Islamist so no link to the far left, but OK, you do you.
At no point has anyone denied a rise in antisemitism (from
both far right and far left), much of it linked to the Gaza war. But the conflation of criticism of Israel with antisemitism BEFORE October 7th as a deliberate protective action by Israeli politicians has created a cover for antisemites and radicals to increase their attacks post October 7th.
The British arms industry (and government) are massively complicit in who they sell arms to and the blind eye they turn on the legal technicalities of not selling arms that are being used in breach of international law on humanitarian conditions. The public though are basically ignorant of the histories of these conflicts, whereas the Palestine-Israel conflict is much better known. I have no real idea whether the SAF or the RSF are the good guys or the bad guys in Sudan. As far as I can tell they are both bad guys. So who do we protest against and to who? the war in general? The Saudis for their despicable role in the region? The British Government for their role in this? BAE and the UK arms manufacturers?
Yemen the same - the PLC or the SPC? or is it the SRC? Are the Houthis really as bad as the USA and Israelis say they are (in a regional context) or is that geopolitical grandstanding to serve their and Saudi regional interests against Iran? So again, who do you protest against and where?
Palestine is much more binary. Hamas are horrendous but so are the actions of the Israeli government since before Hamas was created. The self-determination issue is clearer as well. The illegality of the occupation (UN resolutions, International criminal Court rulings), the basic idea of sovereignty that Israel ignores to bomb the Lebanon, Iran, Qatar, Syria etc allows more people to have an opinion (justified or not) that they just don't have for the other issues you compare it to.
None of this makes protesters antisemitic or even the deliberate catch-all slur of 'far left'.
Be fascinated (genuinely) to know what your opinions are on the rights and wrongs of Yemen and Sudan as I have read up and followed this all the way through and I genuinely don't have an opinion on what a fair and just outcome to either of those conflicts are. I do for Palestine though.
