Sigh to all the answers you received to this question. More excuses from white America. The one that infuriated the most were the users who went on about the Atlantic Slave Trade:
First of all, light versus dark enslavement was NOT practiced by blacks and other blacks. It was practiced by whites in which they treated slaves who were darker even worse than the slaves who were lighter. In addition, the slaves that blacks bought in America were they're family members. If you all would open up a history book instead of just running off at your mouths, you'd know that whites separated black families during the slavery days and thus when a black person won there freedom and wasn't sold back into slavery or murdered which was often the case, he'd go buy his family members so he could live as a happy family with them again. Of course there really was no living as a happy family throughout those 4 centuries of American slavery.
Then we have the countless whites who defend all the anti-black atrocities of white Americans by stating that blacks in Africa have enslaved blacks. First of all, African "slavery" as it was translated over in English was hardly "slavery" but indentured servitude. In no way was African "slavery" as beastly as American slavery. African slavery did not involve treating slaves like garbage, abusing them, nor racial degradation; rather, African "slaves" were very much respected: heading tribes, being paid a great deal in wages, accumulating properties, rising to kings, etc. Blacks had no idea what they were getting into when depraved white Americans brought them over to the U.S. They thought American slavery was going to be the same as African "slavery." They didn't expect all the racial-based, inhumane treatment they were in for from white Americans for the following 4 centuries.
Besides, slavery is only one of the many forms of mistreatment white Americans employed in racially tormenting African Americans. The issue blacks have with whites isn't just limited to their anti-black slavery, but their many different forms of ANTI-BLACK atrocities, ranging from relentless racial slurring/degradation, banning blacks from all things good, separating families for life to lynching, fire hosing attacks, tear gassing attacks, setting attack dogs on blacks, welting up the bodies of blacks with bull whips, stonings, bombings, rapings, burning blacks alive, cutting open blacks, jailing blacks for such offenses as looking whites in the eyes or stepping on their shadows, tarring and feathering, etc, which were all based on skin color and legalized by whites. Slavery and blacks being worked like dogs without being given anything positive in return is hardly everything that went into the anti-black savagery of white Americans.
Let's try to understand where these whites are coming from when they use blacks enslaving blacks to justify whites' racial enslavement of blacks. Let's say that that the enslavement of blacks by other blacks was just as grisly as the racist enslavement of blacks by whites. With that said, whites have enslaved each other in Europe as well. Going by the logic of the above defense, it would be acceptable for blacks to carry out slavery against whites out of racism. After all, whites were enslaving each other over in Europe so this makes it perfectly acceptable for blacks to do the same to all whites out of contempt for their skin color. This is the logic behind the above defense that many racist whites use.
