In the US, 1930s invention of good whites and an apparent common culture excluding non-whites and bad whites (i.e. Nazis). Used to rally white saviour complex to lead world and also fight Nazis who threatened Anglo dominance and business interests. Taught in universities as foundation for everything that's good in modernity.
We must protect Western Civilization (i.e. white male capitalist normativity) from those feminists and third world intellectuals...and of course the commies who want to 'share the wealth'.
