Objectivity & understanding the past in its entirety not cherry pick the past to move on from the past & not repeat it. Understand that Slavery was practice by every ethnic group on the for 10,000 years.Acknowledge & respect that Europid society in Europe & the Americas abolished slavery. Acknowledge that Arab & Congoid Africans are responsible for trading Congoid African rivals, criminals & outcast to the East Arabian Slave Trade & the Trans-Atlantic Slave Trade. Acknowledge that Congoid world population grew from less than 30 million to 1 billion+ from 1500-2020 because of Europid Privilege: industrialization, science, technology, medicine, surgery, food preservation (bottling, canning, plastics), academics, economics, 'Out of Africa' & Europid pursuit to abolishing slavery. (Pre Columbian Human Population: China 100M, Japan 12M, Korea 6M, Mongolia 5M, Europe 50M, Africa 30M, Central Asia 20M, S. Asia 50M, S/E Asia 25, Australia/Oceana 1M, Siberia 1M, Americas N/S 25M)
If Europeans had not sailed beyond the Sahara desert there may not have been a Trans-Atlantic Trade directly with Sub Saharan Villages or Kingdoms, the Arabs would be a monopolized middle men with the product castrated. If Europeans & Arabs left the Sub-Saharan Sub Continent alone to their own device & survival, Sub Saharan population may not have grown to 1 billion & remained at 30-35 million due to endless tribal warfare, tropical African disease, sacrificial voodoo (witchcraft) cults/religions, & exhausted resources. Development into an Advance Society may not happened, just as it didn't with uncontacted tribes in the Amazons & N. Sentinel Island.
Understand that proudly preserving one's ethnic Culture, History, Achievements & Contribution should be acknowledge & accepted with respect as every ethnicity engages in these behavior of bragging rights no matter how huge or miniscule their cultural impact is in the world. Middle Eastern, (Hebrew, Arabs, Turks, Persians), East Asians, South Asians, & Europeans are very proud groups due to their Ancient History & revolutionary achievements. Middle Eastern Civilization had a head start in building Civilization, but was surpassed by Asians & Europeans shortly after. At the advent of the industrial revolution due to Newcomen & Trevithick's Steam engines, Europe & Europeanized America & Australia left every great civilizations behind, until when China reclaims it, if. Amerindians built their own impressive civilization, but were still far behind middle Eastern, Asians, & Europeans due to the lack of Iron tech/metallurgy, written language & the wheel until contact with Europeans.
The practice of slavery was universally accepted world wide for 10,000+ years. African's, Amerindians, Middle Easterners... committed massacre's to acquire slaves. Abolitionist Shakers, Anabaptist, & (R)s viewed it as something that shouldn't be practiced any longer, while the (D)s viewed it as an accepted practice sanctioned & allowed by god since Biblical Abraham. Both side felt they were in the right, but (R) abolitionist ideals won. Socialist & BLM Supremacist are labeling all descendant of European descent (including arrivals after 1865-2020 half descendent from emancipated serfs) as eternally racist because the Founding Fathers bought slaves from Africans that Europids later emancipated.
Serfdom, Caste, & Chattel were 3 types of slavery practiced. Serfdom was when the family or clan & their descendants within the land owned by a lord or lords are enslaved by whom ever owns the land or who it falls to. Chattel Slavery is what revisionist claim was exclusive in the Americas only. Chattel Slavery have been practiced in Ancient Rome, the Middle East & Africa before Columbus. In the 7th Century Islam turned the male Congoid Chattel Slaves into eunuchs. Just like in pre-Civil War USA, Slave owners in ancient Rome can free their slaves. In Islam the slave has to convert to Islam, but great exemplary sacrifice to the nation's society was required (militaristic conquest/defense). Trans-Atlantic & East Arabian Slave trade, Arabs, Arabize Congoids, & hunt/gather Congoid Kingdoms or Villages did the dirty work of massacring 1/2-2/3rds of the villages they raid or conquer to obtain the slave. Caste slavery is probably the worst form of slavery where a clan or entire tribe & their descendants are restricted to only one profession for the rest of their existence. In present day India intermarriages between couples in different caste can lead to Honour Killings carried out by their 1st of Kin.
The push to abolished slavery world wide would not have been expedient if the US Civil War hadn't Happen. England abolished slavery in the late 1700s (Serfs)- early 1800s (Congoid). Russia abolished slavery & emancipated Russian Serfs (Europid Slaves/Slavs as Eastern Europe didn't have African Slaves) in 1862. USA Abolished Slavery in 1864. Brazil abolished slavery in 1890s but continued it with the Xingu Amazonian Tribes through 1920s for rubber. The Russian waves of Immigrants in the late 1800s & early 1900s before the 1914 Russian Revolution were most likely former Russian Serfs/Slaves turned indentured servants. European slaves existed since 3K BC & there were European Slaves up to 1880s in Turkey when the Sultan abolished slavery for Europeans (mostly Crimean, Circassian, Ukrainian & Slavic States) & Congoid Slaves. When Russia turned Communist after the Russian Revolution: Royals, Nobles, Aristocrats, commoners, & former Serfs were subjugated into state bondage forcibly or voluntarily. Southern Europeans in Spain were enslaved for 800 years until the late 1400s when the Moors were expelled from Spain. European slaves gradually got their freedom before WWI, but could've persisted until 1964 when Saudi Arabia Abolished Slavery. Europeans growing strength from their technology & push to abolished slavery globally likely convinced Islamic states in N. Africa & Arabia to end caste/chattel slavery in 1964 with the exception of Mauritania where it continued until 2007, but slavery continues in N. Africa, Yemen, Sahel... as Al Jazeera reported just 5 years ago.
Journalist Keith Richburg Author of Out of Africa 'Thanked God for Slavery' bringing his ancestors to the USA. Africa was the 'worst' continent for Congoids & Capoids before the Portuguese sailed around Africa & set up trading ports with costal Bush kingdoms. Tribal warfare controlled population through sacrificial ceremonies that may involved having to consume sacrificial offerings, a practice that still exist. Joshua Blayhi (Gen. Butt Naked) being notorious for conducting these sacrificial ceremonies as its High Priest in Liberia (VICE: Cannibal Warlords). In Tanzania Albinos, mostly children, are killed for their body parts as charms, souvenirs, & even consumed in the same manner that Gorilla hands and feet are sold as charms or souvenirs, the rest being consumed in the beliefs of gaining some powers.

With the arrival of Arabs (1000CE-1100CE) in the interior of Sub Sahara then Europeans (1500CE), it became more profitable for Congoid bush kingdoms to sell rival bush kingdoms, tribes, criminals, & peasantry. After abolition of slavery swept Europe, N. Americas, then central & S. America 20-40 years later Congoid bush Kingdoms, later republics, still had a reliable slave trading partner with Arab & Arabize nations for another 100-140 years (Saudi Arabia (1964), UAE (64), Zanzibar (64), Mauritania 2007). The most famous slave market was in Egypt well into the 60s. Sunni Islamists ISIS, Al Qaeda, Boko Haram, Libya... brought back open market slavery in their territory & Caliphate. Europids tried to develop/build Sub Sahara Africa. Now China may finish where Europeans left off.
Oprah's racialist delusion had argued in an interview that Racist southerners murdered hundreds of millions of slaves at the time when slave population not more than 4 million before slavery was Abolished. Slaves were worth more alive than dead at least in the Americas as they cost a fortune for most people to afford & maintain. Prior to the end of the US CIVIL WAR, the US had 3.5-4 million slave population owned by 1%+ of the free population of 40 million at the end of US Civil War. 28% of Louisiana & Mississippi had Congoid plantation & Slave owners. Congoids replaced the Caribbean Amerind population. US Congoid population grew 20x than the Amerindian population from 4 million (1864) to 40+ million (2020).
As for reparation, African Countries bares the responsibility for reparation in the form of a an independent sovereign territory the size of Puerto Rico or Hispaniola in Africa for Africans (Arab & Sub Saharan) stealing the territorial lands from those they sold to the middle East, N. Africa, India, Brazil, Caribbean, & the USA. Since the Civil war was financed by Europids, Emancipation of slaves was Given, Not won, & 22 trillion spent to fight poverty to educate & help Congoid communities improve & be self reliant isn't working, then a territorial area the size of Puerto Rico is more than enough for an independent sovereign state as there were only about 4 million Congoid descent in the end of the Civil War. Liberia was the promised land for freed Congoid US Slaves that's 15x bigger than Puerto Rico & negotiating for 1/3 of Liberia will provide more green space.
