Where have you found a hard copy? (I can still find digital copies on Russian websites, like Libgen)
It was not just Amazon. When I initially searched for it, I found several retail outlets where I could buy the book.
The big tech companies censored positive reviews, podcasts, discussions of the book, his social media profiles, etc.
It has even been burned from many review/book catalogue sites: NOT A BOOK: Sanction I by NOT A BOOK
Yes, that is it.
I know the book has likely been accused of misinformation, racism, wrong-think, misogyny, being an anti-vaxxer, anti-semitism, being a conspiracy theorist, Q-anon schizophrenia and witchcraft.
I watched a couple of podcasts he did before they were censored from the internet; he came across as a highly intelligent, independent thinker, unafraid to write about novel ideas and theories.
The events that led to the shooting in Denver are not as simple as the "crazy guy" narrative in the media:
He had a dispute with some of his business associates, went bankrupt and the courts refused to hear his case, ruling that he lacked standing. He increasingly became convinced of the injustice of state bureaucracy and the disenfranchisement of many multi-generational Americans.
Before last month, the book was considered by its fans to be the next "Fight Club".
That voting requirement would fix a lot of problems.
However, the point both I, and the book I brought up, make on the topic is one of biological realism; Can you govern an Englishman the same as you would a Scotsman?
The most basic biological imperative, as Mcclay said in his book, is this: "Pain demands a response"
That genetically determined pain may spur a Scotsman to act, while the Englishman lays passive.
As individuals, humans are highly adaptable, but as aggregates, stereotypes prevail. Genetic determinism influences the behaviour of both.
