Be in no doubt. The Royal Institute of British Architects (RIBA) is now officially antisemitic. On Wednesday, it voted to support a ban on Jews from joining the International Union of Architects. It didn’t put it quite like that, of course. The wording of its motion referred to ‘Israelis’ rather than ‘Jews’. But in singling out the Jewish state for opprobrium, over and above every other nation on earth, and in seeking to ban Jews — sorry, Israelis — from membership, the driving force behind both the BDS campaign and its RIBA conspirators is clear. Jew hatred lives on in RIBA.
