And fascism ended up killing fewer people than the British Empire, USA, or French Empire and it wasn't tried again for 80 years.

As you say, people are shockingly tolerant of terrible things. Especially when there is a socially constructed boundary between them and the victims (race, nationality, etc.). If you count nonwhite noncitizens as full people, fascism was less deadly than liberal capitalism.

Do we care half as much about the death of a dozen people at a wedding in Pakistan as we care about Alex Pritti? Do we care half as much about the colonization of north America as about the Lebensraum doctrine? Do we care half as much as about the British colonization of India as about the holocaust and WW2?

Fascism is capitalist abusers coming home. it is horrible, as capitalism always was.

I would prefer capitalism to fall without a fascist period - not the least out of self-preservation as a white citizen of a first world country - but at this point every decade that capitalism survives is another billion dead from climate change.

If we stave off fascism by embracing liberal capitalism, all our children and grandchildren will die violently. It can not be enough.
