This is true, but the real reason that black brazilians are still able to maintain some of their native customs, which was left out of your post, is because of the short life expectancy of the brazilian slave.
Brazil had the most slaves of any slave owning country in history. Thats because the black slaves were LITERALLY, herded, breeded, and worked to death, LIKE CATTLE. The average life expectancy of a male slave was 32, and if they were born a slave in brazil, it was even shorter.
These crackers LITERALLY beat, killed and worked to death ALL BLACK PEOPLES, males and females. They didn't bring wives, if they even had families; so they raped the women (some "wifed" them because there were no women besides the slaves). Seriously they SLAUGHTERED Black men, women and children, like fukking cows. This is because IT WAS CHEAPER TO JUST BUY MORE SLAVES. There was no incentive to treat these slaves like your work force. This is why the brazilian blacks are able to maintain a culture, because there was a fresh crop of new slaves every season.
THIS IS HOW AMERICA DIFFERS. THEY TWEAKED THE WHITE SUPREMACIST SYSTEM TO PERFECTION.
They took lessons from brazil on HOW NOT TO RUN YOUR SLAVES. At one point USA imported so many slaves, that their was more slaves than the white population. They said fukk THAT! Theres to many of these ****ers , they might stage a revolt.
America started to import LESS, and LESS slaves. And started breeding them. without the influx of new slaves, this destroyed any cultural connections among blacks. Then they brainwashed us. Then they controlled the numbers in the black population. Then they created a managerial system of hard labor, and deadly consequences.
