Don't think like that otherwise you'll be just as backwards as some of them... many of them are.
Also, you do know that every ethnicity has enslaved those of their neighboring country at their time in history as well as oppressing their own people.
The British enslaved their own people and they also enslaved the Irish. There were white slaves too. When criminals of Britain would commit crimes if the crime was severe they would be banished to Australia to help build Australia up or on the slave ships with the West African slaves. This is documented. Egyptians enslaved their own people. The Moors enslaved parts of Europe and Asia in particular the Sicilians, Portuguese, why do you think their skin is so tanned? as well as The Moors being the first to inhabit parts China and were the original inhabitants of Japan before the pale Chinese people took over the island centuries later.

The only reason why black people are so stigmatised now is that slavery as we know it from the the last 500 years is the most modern one at such a large scale.

The modern history books are written by old white men with an agenda to lead you on to believe that they are superior in society when in truth every civilisation eventually crumbles and it always ends through war of neighboring tribes, clans, countries.

It has happened more times than you can think and it always ends the same, with revolt. No one wins in the end.
