According to Darcy Ribeiro, the Brazilian racist assimilationism is perverse because it gives the impression that there is a greater social acceptance of people of color. He suggests that by dividing the African-descended population into ranges of skin colors, ethnic solidarity is reduced and they lose political power. He contrasts it with the racial segregation in the United States, which ultimately united all the population of African descent, regardless of skin color. He believes they developed a deep internal solidarity of the discriminated group, which enabled many to fight for their civil rights. But Ribeiro also says that what he describes as the US Apartheid model is worse than Brazilian assimilationism when other aspects are considered).
