1. As mentioned, white man's burden and in general a common theme in the late 19th/early 20th century
2. Probably neoconservatives as mentioned, but also the sort of conservative/far-right types who really like Putin, Orban, Assad, and other strongmen. Maybe a religious variant where Christians and Muslims and other religious conservatives team up to stamp out "social ills" like feminism, porn, anything LGBT, etc. IIRC there used to be a lot of Muslim Republicans in the US before 9/11 so there might be something to this.
3. Blend anarcho-primitivism with anarcha-feminism and you basically have this, but add a bigger emphasis on matriarchy rather than simply getting rid of hierarchies.
4. The trick is turning it into an ideology. Racists love to deplore the supposed acts of other races, and there are examples of pacificists who could be called racist.
5. Basically modern social democracy
6. Could appear in Germany or Japan after 1945, assuming you get enough intellectuals wanting to both sweep their war crimes under the rug AND inject copious amounts of postmodernism right into the bloodstream (difficult given the left-wing slant of postmodernism and the German/Japanese postwar left). Makes more sense than anti-Japanesism or the similar German ideology.
