Mr Bradwell said Mr Graham-Dixon offended members when he used Hitler's "deplorable" words about Jewish and black people in his speech.
He later said: "We will create a blacklist of speakers never to be invited back, and we will share it with other unions too. Andrew will be on that list."
It is good that Mr Bradwell appears to have changed his mind but I would like to ask Mr Bradwell his views on not allowing speech that would be offensive about black people, while employing the term "blacklist". The English language is full of phrases and descriptions that say black = bad and white = good. I would enjoy seeing him try to unpick that.
