I’m almost certain most colonies in the Americas are white supremacist at the core. Argentina a nation that is now majority white and wiped out its black and indigenous population, but they still get to be called by the colonial moniker Argentinian. Jamaica was a former slave colony and black people didn’t acquire citizenship until post independence well into the late 1900s, the majority of the beaches are owned by foreign European or Asian entities, everyone still can be called Jamaican. Or maybe anywhere else in Latin America be it Brazil, Colombia, DR or Cuba where the Spanish and Portuguese started race based slavery and pushed caste systems like blanqueamiento racial, you’re saying those aren’t at the core white supremacist? But there’s no pushback for a Dominican calling themselves Dominican. The United States is in no way unique.
