The people on Stormfront and other nationalists say the same thing for our ideologies.
While this is a powerful statement, it's partially untrue. Remember that people are products of their environments.
It's sad, I bet a lot of these people on Stormfront are only there because they see no other solution to the fault of their respective governments other than purging minorities and the supremacy of their culture and they have fallen to propaganda because there is no revolutionary movement or thought in their area. Or maybe they grew up with racist parents and nationalism and other prejudices are an inherent part of their thought because of how they have been raised.
It's not just a case of saying "they're all insane/ignorant/retarded/stupid", though I don't think everyone on Stormfront or all those who subscribe to some fascist/nationalist ideology may be the sharpest knives in the drawer, smart and sane fascists exist. But they are just confused products of their material conditions.
Don't be irrational like they are.
