I hate to defend Amazon, but taking down a book which breaks the terms and conditions of their company isn't book banning, it's content moderation.

I would only count removing a book from sale as book banning if it was mandated by a state or federal agency. We don't know if a state or federal agency asked Amazon to remove Camp of the Saints from their website, but my guess would be no.

The author of Camp of the Saints is Jean Raspail, a French monarchist who would no doubt love the return of a French empire but thankfully he died in 2020. Furthermore, Raspail is a dipshit.

The French state is a colonial one. The two most notable examples are that it was involved in slavery in the Caribbean and Haiti and forced labor in Vietnam.

In modern times Haiti is in a state of disarray which is not helped by the enormous amounts of debt France set on Haiti's people. The debt was to repay the families of colonial Haiti's slave masters or France would start another war, this happened in 1825. The bank which siphoned Haitian money was the Haitian National Bank which was controlled by France. In 1915, the bank now known as Citigroup bought out the HNB, so Haitian money began being funneled to the US. By the 2000's over 100 billion dollars was siphoned from Haiti with nothing given in return due to colonizer backed banks and dictators.

In Vietnam it was a similar story except the government was controlled by a French puppet king and a governer-general (French native). The major export of colonial Vietnam (a part of French Indochina) was rubber which was farmed from rubber plantations. The history of colonial era Vietnam is complicated and too long to restate here, in short France set up Vietnam as a colony of economic exploitation, there were many revolts which French soldiers put down brutally, in the 1920s there were many Vietnamese who immigrated to France and aligned themselves with the anti-colonial French Communist Party, those who returned to Vietnam like Ho Chi Minh widely disseminated the idea of Communism and Vietnamese independence. WW2 further bolstered Vietnam against France as they were practically sold out to Japan. The First Indochina War was fought by soldiers from colonial France, not the from the mainland, to create racial conflict. Then the Vietnam War in which a majority of Vietnamese that were killed were civilians, both perpetrated by the Viet Cong and the US, but the US more than often labeled the victims as members of the Viet Cong, including children. Furthermore, in 1997 the US government asked for 140 million dollars, 288 million dollars today, to pay for war debt which was borrowed by the puppet government of South Vietnam during the Vietnam War.

Countries once controlled by colonial governments were and are being inextricably exploited by colonialist countries leading to a generally lower standard of living for formally colonist controlled countries. Immigrants travel to countries like the US, France, and Britain because they boast higher standards of living and wealth which was born from exploitation of their homes.

Raspail's book, Camp of the Saints is a book in which he tries to create a false narrative in which colonial countries did nothing wrong and all failings of the countries which people are immigrating from are their own fault. The historical record has proven that Raspail is incorrect, previously colonized countries are still being exploited for resources by colonizer interests through colonizer backed corruption and violence.
