You all touched on everything but the one most fucked up thing Europeans invented that endures to this second.
They invented the pseudo science of race and conditioned various sub Saharan Africans they were "black". And the truly most fucked up part of it is that what makes race real is ADOS.
Ive posted this in previous threads about how the invention of race affected ADOS...
The 3rd greatest crime against humanity that cacs committed in the New World besides genocide and human bondage was the stripping of identity of a group of people, something thats almost unique in human history as far as I can tell. As fucked over as native groups were in their lands (native americans, aborigines, ainu (japan) central and south american peoples, filipinos (south east asians) etc) they still had some connection to their original identities, culture, language, religion even if they had to mask it in cac shit. In fact its been noted that the slave rebellions in the Caribbean were successful because those enslaved people had a stronger connection to their identity more so than the mainland american slaves. Even as they used European religion and culture as a cover (santeria for example).
Africans Americans lost our heritage, language religion etc its why you see us searching for ANYTHING to connect to and feel positive about ourselves whether thats asiatic, moorish, egypt or redefining a skin color designation whose original purpose was for oppression and subjugation. Something else I said before...
When all your taught in a racist system is that you come from nothing and produce nothing...you start looking for yourself in everything. Hence Hebrew Israelites and Moors and Egypt and pretty much anything that exhibits thick lips and dark color.
The creation of race as a concept combined with the Atlantic slave trade really kinda created a whole new group of people. The specific origin of race as a concept is pinpointable to time and region and country. Unfortunately what makes "race" real today is ADOS...Black Americans.. what I mean is the skin color designation we were given solidified the concept the second the generation after those enslaved Africans either forgot, were never told and/or rejected any knowledge of who they were and where they came from.
Negro is spanish for black...ngger, nigga, nigra etc is just a bastardized slang for negro=black it all comes back to the same thing.
Maybe that explains why pretty much every other group (to my knowledge) does not use the slur pertaining to them in their pop culture to the degree that black americans do. The n-word permeates every aspect of our culture and entertainment to the point where its weird if we DON'T hear it uttered at some point.
But unlike pretty much any other group in american society you have one group thats been completely cut off from its original heritage and ethnicity and MAYBE thats why the n-word flows so easily from the descendants of the african slaves because thats what we've been called more than anything else in this country..its a part of our AMERICAN history.
