Klein found in Operation Shylock a mirror of her own doppelganger predicament

Evidence

The reason I began defacing the book—with underlines and asterisks and exclamation marks—the moment it arrived is that Operation Shylock explores, with frankly uncanny precision, many of the bizarre mental and political traps I had been experiencing ever since my own doppelganger problems escalated. The cringe of confronting a parody-worthy version of one’s self. The catch-22 of defending one’s personal brand. The fascistic shadow selves doppelgangers can reveal inside ourselves. The way whole societies can have sinister doppelgangers. The novel contained all of that, and more. — Naomi Klein, Doppelganger, 459

Categorization

• XREF: This is where Klein explicitly names what the doubling device is doing for her method: ‘the catch-22 of defending one’s personal brand’ and ‘fascistic shadow selves’ — the analytic payoff of the confusion. Directly serves the reader’s purpose of tracking the device.
• QUESTION: Klein lists four traps the novel captures — the reader should watch whether her own Israel/Palestine chapters actually deliver on the last two (fascistic shadow selves, sinister social doppelgangers) or whether the device strains there.
