Corbyn liked a Facebook post that showed a mural with antisemitic "global banker" tropes, didn't he?

I am a bit curious anyway as to how Baddiel came to the conclusion that Corbyn somehow escaped criticism in comparison to Rowling - the perception of his failure to deal with antisemitism was surely one of the major reasons for his overall defeat: he took enormous flak for it from almost every major news outlet as well as on social media.
