Sounds like the guardian wanted to get rid of him for a while. Apparently he has been involved in antisemitism incidents in the past. They don’t need the controversy he brings.
Perhaps he can get a job at the Daily Mail.
The Guardian was started by Unitarians who are supposed to be open to ideas, but now it fully embraces cancel culture and censorship, like any orthodoxy.
Ah, a conservative favorite. No thanks, I’m not in to mindless cruelty like right-wingers.
