I agree that, to some extent, this book is PWME-bait. The attempt to whip our community into a froth to help publicize the book (and point out 'hysterical' patients) is practically hanging in the air.
The reason she's won the prize is not because what she has written is imaginative and groundbreaking, but rather the opposite: she's trotted out the same, tired old tropes that Freud pioneered back in the day. Even Freud was putting a pseudoscientific spin on the spiritual sensibilities of the time: that sensibility that gave us the wildly popular seances and pseudoscientific magnetism/electricity studies of the era.
She's won because she's supported the view that the establishment wants to see promoted. She's writing about the status quo.
I'm not sure we should say or do anything in an official capacity. I would answer tweets as above, and I would write in anywhere someone has her on a radio show or where she is promoting her book, with an emphasis on short, well-reasoned responses rather than the outrage people may expect to see.
I say this not in any official capacity as #MEAction staff... just as an individual who thinks it's pretty clear we're being baited. She hopes this will be a controversial and popular book that everyone will be talking and arguing about. What better response than cricket-silence?
