Yes. I truly believe that self-loathing is a challenge all African peoples who lived during the aftermath of colonization, enslavement, segregation, and Jim Crow had to deal with at some point. People of color were considered inferior, and, at some times in our history, sub-human. The darker you were, the more sub-human, the more animal-like, the more ignorant and incapable of intellectual achievement. It was an intentional degrading by the 'others' to sublimate, and it worked! Dominicans are not the only people of the diaspora who did not want that label.
I agree. I believe Dominican have an extra layer because of their history with Haiti.
