What the heck are you talking about? Learn how ethnic groups are formed. No duh. Chattel(its not spelled chattle) slavery. But the fact is African-American history is MORE than just that and during that time(again), the AA ethnicity did not even form yet. But also the fact that we are arguing IF those "Freed Colors" were descendants of slaves is another point.
More importantly, the Freed Colors skipped most of the Reconstruction era, Jim Crows, Black Codes, the Civil Rights movement, etc. I'm about to read a book(haven't gotten to reading it yet) called Post Traumatic Slave Syndrome where the author addresses the many trumatic events that AAs went through, in NOT JUST slavery but also Jim Crow and after. Those Freed Colors did not go through that. Its highly doubtful they even carried this trauma.
What the heck are you talking about? We're talking about a collective group. And not individuals.
Its only laughable and disrespectful in your limited brain.
