I don't know you, so I will not say that you are incredibly uneducated. I will just say misinformed with some slanted prejudiced and wrong information.
Yes, racist people are everywhere, north, south, east and west. The entire world until the industrial revolution were dependent on farming, however having slave labor to do it was mostly a Portuguese, Spanish, French and English thing in the western hemisphere with black African slaves. Throughout the history of mankind, slave labor was not how farming developed for the masses.
The Trans-Atlantic Slave Trade WAS NOT conceived by Africans. Africans did not conceive it, develop it, build ships or forts, nor did they profit prodigiously from it. The Trans-Atlantic Slave trade did not start with a transaction. The Portuguese stole Africans that they captured.
Also slavery in Sub Sahara Africa was a completely different than chattel slavery in the Americas. In Africa, you were a slave due to unpaid debts or a prisoner of war. Your term of servitude was not passed on to your children and your children's children and it certainly wasn't based on color. You had rights in many circumstances.
How did the largest forced migration in human history start?
In 1441, Portuguese Prince Henry "the navigator" dispatched two knights, Nuno Tristao and Antao Goncalves to explore western Africa on separate ships. Goncalves was filling his boat with seal pelts on the coast and ran across a camel driver. When Tristao meet up with Goncalves, Tristao had a Moor servant and asked him to translate and ask where gold was. The camel driver pointed them in the direction of a nearby fishing camp. Goncalves promptly kidnapped 10 Africans. The next day he paraded them naked to lure out the villagers in an attempt to capture more. Tristao and Goncalves were ambushed by over 100 warriors and high tailed it back to their ships. Goncalves went back to Portugal and Tristao kept going south, but later returned to Portugal. He saw that Goncalves had profited highly. His big profits weren't from selling the seal pelts, it was from selling the 10 stolen Africans. Tristao on his 2nd voyage, 18 months later to Africa he captured more Africans, including a Chief. He then bartered the Chief for 10 more Africans and exchanged the Chief's release. He sold the Africans back in Portugal. At this point Prince Henry figured this was a profitable business and sent Tristao and other expeditions to Africa to capture more Africans to sell. Tristao was killed by Mandinka warriors in 1446 in the Gambia trying to steal humans.
Prince Henry set up Casa da Guine' and for the next 50 years imported goods from Africa to Portugal, with the most profitable being the 1,000 slaves a year. The Portuguese justified the stealing and enslavement of Africans by saying they were converting them to Christianity. The Trans Atlantic Slave trade started when the Spanish and Portuguese started colonizing the western hemisphere and need labor for the crops. They had killed the natives in Central and South America and Caribbean Islands from war and infection, so they didn't make for good slaves.
Back to that repeated lie that it started by Africans selling Africans is complete BS nonsense. If some hadn't sold their indentured servants and POWs, they would have been enslaved themselves, as was the Queen of Dahomey enslaved by the Portuguese.
If it was just a transaction, then explain why Europeans never left Africa and colonized Sub Saharan Africa? King Leopold II enslaved Africans in Africa!, the Congo and most Sub Saharan African nations didn't gain their independence from their evil colonizers until the 1960's and 1970's, in the borders that were mostly drawn up in the Berlin Conference.
Stop saying and implying that African slaves and their decedents are slaves by their own doing, they weren't. Also, not one single slave and black person since has ever done anything that deserves 4 centuries of enslavement and subsequent 2nd class treatment after emancipation.
