They like to make us think in the Netherlands that Amsterdam was build upon slavery money, the Dutch only controlled like 5% of the slave trade. Most of our wealth was gained by trading bulk goods like grain and fur with other Hanze league cities. Its all done by guilty whites that want to give blacks something to be proud of, they want them to think it couldn't be accomplished without them.
It would be better to say that whites were the most benevolent colonizers in history. Shure whites killed a shit ton of people, what conqueror hasn't done that. But whites brought so much innovation and technological progress that its uninmaginable to think of how society was before whites colonized. Just think about it, before European domination people burned wood for fire now we canalmost use nuclear fusion to make electricity. Horses were the fastest mode of transport, now we have mach 10 rockets and space travel. Medicine was done by rubbing some herbs and cutting hoping it will turn out good, now we have the current medical knowledge. And uncountable other things, but hey we did slavery (just as every other people) and ended it. So whites are evil and the world would be better of without them. But dont forget to praise imperialist muslims, that also did slavery and colonialism.
