Founder of fascism was a socialist

Not surprising. Fascism, socialism and communism are all leftist philosophies. A simple way to look at the left/right paradigm and where one falls in it is to ask if they believe that individual exists for the community or if the community is to exist for the individual. Leftists always take the former.

Mussolini also dealt rather harshly with Neo-Marxist "Antonio Gramsci"; a martyr for Leftists

Pretty much the radical philosophy that has become the guiding influence of the EU,
and gents like self identified "Liberal Socialist" Mario Draghi, and those aligned with the World Forum on The Future of Democracy, Tech/AI and Humankind, and World Economic Forum adherents. C4IR
