What they should have said is 'trans activists are threatening the staff and their children so we are left with no other option than to cancel the show. we have reported the threats to the police as a hate crime for hosting a diverse comedian'.
Not made out that hosting a black comedian was unsafe by virtue of his diversity, but that trans activists were making it unsafe.
They chose those words. We get told that if there are threats then to report them, so if there were threats surely there will be receipts to pass onto the police?
