Aparthied isn't what you think it was. It wasn't because they were black. It was because they immigrated into South Africa without becoming citizens. Its what the Democrats are creating with illegal immigration
Well... it's a lot more complex than that.
Back in the 19th century and earlier, the area was a bunch of different little African kingdoms and Dutch colonies, and they mostly left one another alone.
Then the British Empire came rolling in and conquered them all, and made the Union of South Africa. The main motive for this was: Gold! So much gold!
Just those pesky Boers getting in the way!
Because the Boers resisted, the Empire put them all - their entire civilian population - in concentration camps. I am not making this up.
To this day some among the Afrikaner people probably still believe that it was a deliberate attempt at genocide. (it wasn't)
Now the new capitalist Global World Order's plan for the region was basically resource extraction: black labor being used to dig up that gold, for the profit of international capital. They imposed taxes on the Africans that they could get money to pay only by leaving their traditional way of life and becoming wage-labourers in the mines.
As for the Dutch/Boers/Afrikaners, they could go away and die.
Well, they didn't go away and die. They went and voted in a government - the National Party - that would rule for their benefit, and enact policies to lift them out of the poverty the devastation made by the Empire had left them in. And the NP kept that promise.
As for the blacks, the National Party's Apartheid policy was to give then back self-rule, in the areas where they had been living before the Empire conquered them - thus the homelands or Bantustans.
This meant they would not be citizens of the Republic of South Africa, but of those independent states - Transkei, KwaZulu, Bophutatswana, etc etc. Each Bantu tribe got their own one.
But the main goal of course was the economic upliftment of the white Afrikaner.
In the eyes of the globalists - Capitalist or Communist - this was totally unacceptable! How dare a group of White people put their own survival and prosperity ahead of the abstract ideas of global humanity? That's racist!
Well, actually, the West was in practice willing to work with the Nats as long as that gold kept coming out of the ground. The Communist bloc therefore sided with the black "liberation" movements - which in practice waged a campaign of terror against the very people they claimed to be trying to "liberate"!
Who do you think got necklaced? Answer: black people who were accused of working with the white government.
TLDR version: In regard to the whole
Apartheid thing, the Afrikaner people were and are more sinned against than sinning.
