“slight differences”

First: I don’t believe difference between Nazi Racism and Fascist Nationalism is slight as these ideologies had vastly different numbers of victims, second: I care for factual representation of history

it’s not the slight differences we care about

You should care about them, because those who don’t know the history are bound to repeat it. Generalization of ideas is bad, it both prevents proper communication, and it’s a source of most horrible ideologies.

or are you just trying to defend Italian fascism

Or right, now I’m accused of supporting fascizm. You can’t even have normal discussion about these topics these days.
