Nationalism
Hindu-nationalist ideology in India, in the 1930s, drew lessons from
its contemporary, Nazism. Comparing the two can help us identify the
fascist essence that they have in common.
This suggests the lesson that the specific choice of majority trait
which serves as an excuse to marginalize and dehumanize others is just
a detail. Any trait can be used for this, if its members can get
their hands on power to oppress the rest.
The trait need not even be borne by a majority, except in a somewhat
democratic state which impedes any minority from getting the power to
oppress others.
