Fascism is against your own people, colonialism is against other peoples. It’s got nothing to do with skin colour, it just so happens that a lot of colonialism we learn about nowadays was done by western nations like the UK and US. Or would you argue Saddam Hussein wasn’t a fascist? How about Plínio Salgado?

Uh no lol. I’d suggest reading a history book - any history book - as an introduction to reality.
