The only thing the acronyms cult have delineated from is shame. Africa has thousands of years of documented civilizations, languages, kingdoms, written traditions, and archaeological evidence. Indigenous peoples of the Americas have their own histories, languages, ancestral traditions, and communities that long predate European colonization. And Black Americans have an extraordinary history of survival, resistance, cultural creation, and struggle against slavery and segregation. None of these histories needs to be erased for the others to matter. If you have to invent a story about being the original inhabitants of a continent to feel superior to Africans and Indigenous Americans, you aren't defending history. You're shamelessly demonstrating your ignorance of it.
