That’s sort of all that needs to be said. The European colonial project is the deepest wound currently affecting the world’s people and subjugated 80% of the world’s population in a brutal, racist, misogynist, genocidal regime of hyperextraction, extinction, and devastation. If you don’t feel ashamed of that, there’s not much else to say.
The USA, Canada, and Australia are European settler colonial extensions of the brutal history of Europe. Europe set the indigenous genocide in motion. That the USA decided to create a distinct political regime that broke from Europe does not in anyway break the actual historical lineage with Europe. Even today many of the leaders of America trace their roots to European aristocracy and royalty.
Europe is THE scourge of the world’s people and has been for 600 years. That’s not racism. Europeans invented racism. Fighting Europe is anti-racism. Getting Europe out of where it violently inserted itself is anti-racism. Extracting everything Europe stole from the rest of the world and leaving Europe impoverished is anti-racism.
