Much as I like to blame Tory MPs for everything - this is the fall out of incompetent management by Picador and to be fair KC’s own choices.
An agent quoted in the OP’s article put it:
“It was a group fail,” I think the publisher failed in their duty of care to the writer. I think the author failed in her duty of care to her pupils, and in saying that she didn’t write what she did. Nobody emerges from that story well.”
It should be balanced by acknowlegement of all the poc who were triggered by the book - reviving memories of casual racism from teachers at school. One example is Monisha Rajesh:
“I had teachers like her”… “I had teachers who did absolutely put me to one side as being the small child with the furry eyebrows or the ’tache and they made you feel like outsiders – without necessarily meaning to do it, but they did. And it didn’t matter how well meaning they were, it did make you feel small and it troubled you later in life.”
Of Clancy she said: “You’re not being cancelled, you’re being challenged. You’re not used to being challenged, and, now you are, you don’t know what to do about it. And it’s only going to happen more now that marginalised readers and editors feel more empowered. All it boils down to is: please stop writing about us like this.”
