Deprogramming with Grace's Dad
If you think Desmet is an authority on something, please read this.
This is a long read. It is a reply by its authors to a 'hatchet job' done by John Waters on their critique of Mattias Desmet's The Psychology of Totalitarianism. Waters ironically calls their book review a hatchet job.
While the introduction has links to those shorter reads, this is where they really lay it down.
Part 3 is where they go into how Desmet's concept of 'mass formation' actually comes from Freud.
I believe Desmet's book is for grabbing those people who are mad about what happened and twisting them into a Freudian mind-copulation where they can only blame themselves.
