Members of all racial groups underwent enslavement at one time or the other. However Democrats want to paint that slavery was only committed against the Africans and whites were the only perpetrators. Nothing can be farther from the truth.
The worst atrocities were carried out by the Arabs, who had established a lucrative slave trading business in Eastern Africa for almost a millennium. However, unlike the Atlantic slave trade, very few descendants of East African slave trade exist. Because the male slaves were immediately castrated and made eunuchs, while any children born to the female slaves were killed as soon as they were born. Fore more than 5 centuries, the Tatars and Turks enslaved millions of East Slavs (Russians, Ukrainians, Poles.etc). Barbary pirates raided Southern Europe, taking huge number of Italian, Spanish and Greek slaves.
Repatriations would still be OK, if they are being paid to individuals who were enslaved once. But that is not the case. The demand is that descendants of a particular ethnic group must be uniformly paid handouts, irrespective of whether they are descended from slaves or not.
Here it gets murky. Take the case of the Amazonia region. During the late 19th century, hundreds of thousands of defenseless natives were enslaved by the rubber companies. The owners of these rubber companies were whites. But the slave raiders were blacks (mostly descended from freed slaves) who were imported from the island of Barbados. These black employees committed spine chilling atrocities against the defenseless natives. They would rape children as young as 3 or 4 years and they would cut the limbs off the children if their parents could not gather enough rubber. One of their favorite past time was to lift infants by their legs and smash their head against rocks. If the democrats have their way, then these barbarians and their descendants will be proclaimed as worthy of repatriations and the remnants of the native slaves will be declared as "oppressors".
There were reparations paid to Native Americans - in the continental as well as separately for Hawaii and Alaska. Also to the Japanese that were locked up in camps during WW2.
A grand total of $1.3 billion. That is for 2.43 billion acres of land, and tens of millions of deaths.
