"Don't let your mind speak louder than your heart" - I think many have this so very wrong. Is support for fascism is a sensible, logical, well-thought-out policy? No, it's a heart-felt, emotional appeal to scared, proud, paranoid, crude, brutal people (who seem to be about half of our neighbors). surely the mindful decision is empathetic, constructive, and wise - not just base.
My point isn't that fascism is a good or reasonable ideology. But that many people's reasons for supporting it weren't just emotional. Also that their support for it wasn't necessarily or primarily racial in origin, but based in strong anti-communist, nationalist beliefs, instead.
