European nations tolerated Nazism because it was first used against non-European peoples.

Evidence

At the very beginnings of European civilization (meaning literally the reappearance of urban life at the end of the first Christian millennium), the integration of the Germanic migrants with older European peoples resulted in a social order of domination from which a racial theory of order emerged; one from which the medieval nobilities would immerse themselves and their power in fictional histories, positing distinct racial origins for rulers and the dominated. The extension of slavery and the application of racism to non-European peoples as an organizing structure by first the ruling feudal strata and then the bourgeoisies of the fourteenth, fifteenth, and sixteenth centuries retained this practical habit, this social convention. … Moreover, European racialism was to undergo a kind of doubling onto itself, for in between the era of intra-European racism that characterized the first appearance of European consciousness and the predatory era of African enslavement, is the almost entirely exogenous phenomenon of Islamic domination of the Mediterranean—the eventual fount of European revitalization and recivilization. Independent of the historical meshings of European development but profoundly restricting that development—first in literally retarding European social development by isolating it from civil life, science, speculative thought, and so on, and then, after four centuries, by accelerating its recovery from the twelfth century onward—Muslim civilization mapped the contours of the European cultural renaissance. — Cedric J.
