Radical self-hatred characterizes a growing number of political and cultic movements in the last century. The Khmer Rouge (who deserve more study), the Islamic State, the Anti-Germans, the Voluntary Human Extinction Movement, etc. One interesting case study is that of Anti-Japaneseism. Here is part of an abridged Wikipedia entry:
Anti-Japaneseism. Wikipedia, May 17, 2017.
Anti-Japaneseism (Han Nichi-bokoku-ron) is a theory promoted by a faction of the Japanese New Left which radicalizes the Old Left’s Anti-Japanism.
Differences between Anti-Japanism and Anti-Japaneseism: The Anti-Japanism theory posed that Japan’s actions since the Meiji period had been tainted by imperialism, and a new regime was needed. According to Anti-Japanism, Japan’s moral failure can be redeemed if the Imperial family is purged and the country forcibly transitioned to a communist “people’s republic”. Anti-Japaneseism radicalized this argument by claiming that even communist revolution could not redeem Japan because the Japanese themselves possess an inherent “aggressive nature”. Proponents of this theory believe that the only way to redeem oneself from the “oppressor and criminal Japanese race” is to fight against all Japanese interests until the “Japanese” archipelago has been purged of anything Japanese.
Historical thesis: According to Anti-Japaneseism, the original inhabitants of the Japanese archipelago were anarchist agriculturalists, but were invaded by an equestrian tribe from whom the current imperial family descends. Those who resisted the conquest became burakumin. The suppression continued through the 19th century as the imperial regime conquered the Ryukyuans and Ainu. Thus, the history of Japan is defined as “a history of invasion and exploitation”.
Final Solution: The so-called “final solution” of Anti-Japaneseism is to wipe the nation called “Japan” from the face of the earth and exterminate the Japanese race. Because, as described in the above historical theory, Japan is inherently evil, the continued existence of Japanese people is incompatible with peace. East Asia Anti-Japan Armed Front member Yoshimasa Kurosawa affirms that he is not opposed to any particular Japanese political regime, but to the existence of Japan itself.
[…] The activist who came up with the name “Anti-Japaneseism” has since left the group and describes it as “Satanic”.
[…] It has been suggested, however, that this ideology has provided the basis for several ongoing leftist protests as well as Aum Shinrikyo’s gas attacks.
