Two years ago I wrote an article where I warned the IHRA definition of antisemitism would be used to restrict academic freedom. I therefore urged universities to drop it: https://web.archive.org/web/20210512141702/https://www.tcs.cam.ac.uk/why-we-should-drop-the-ihra-definition-of-antisemitism/
The article, quite predictably, outraged many people. But though stupidity and prejudice might triumph in the short term, truth and reason triumph in the end.
My arguments have been validated in a report published this month by the ELSC and BRISMES: https://www.brismes.ac.uk/files/documents/Freedom%20of%20Speech%20and%20Academic%20Freedom%20in%20UK%20Higher%20Education-BRISMES-ELSC.pdf
