Dos Santos and Joaquim Barbosa Gomes, a constitutional law professor and lecturer at Columbia University, say racism is more easily detected in the United States than Brazil and is thus harder to combat. Affirmative action's advocates chide dos Santos Silva and other cautious Afro Brazilians, noting that blacks have been "feeling different" since an estimated 3.6 million slaves toiled throughout the country from 1532 to 1850. That estimate does not include the captured Africans who did not survive the brutal journey to Brazil by ship.
The Cuban journey on race relations denotes an adventure driven by ideology. A doctrine of equals and the need for consensus building towards national unity called for the reversal of disenfranchisement commonly practiced prior to the revolution. Public policy has affirmed a commitment to social integration of people of color yet the residue of bigotry still inflames the Cuban populace and stymies potential maturity among its people.
