She's an academic with a book to sell.
She's not particularly different in that respect to a myriad of other academics, politicians, newspaper columnists etc
It's about a fairly controversial subject, so she's cooked up an angle that the uninitiated, the already converted, and the self righteous and those incapable of any analytical process will lap up.
I wonder sometimes how charlatans like her sleep at night, and how anyone who actually accepts this crap at face value manages to dress themselves in the morning
