If ignorant American present falsehoods about Europeans, then we have every right to correct that, without being accused of being "self centered."
Of course white supremachy has played a historical role, but doesn't mean that racism isn't more than white supremacy.
There is an American attempt to reject all forms of racism that does not fit into the narrow American definition and understanding of racism.
And world history is more than just the history of European colonization of other countries.
European power did not just colonize faraway lands, they also occupied and subjugated each other. Most European countries are not great power with large colonial empires. A lot of us lived under these empires just like black and brown people elsewhere.
Nor is colonialism a unqiuely European phenomenon. China, the Arab world, Aztechs, Incas, Japanese etc all have engaged in variants of it. European colonialism is simply far more visible because it happened in relatively recent history and Europe has been so militarily, technologically and economically dominant the last few hundred years that their impact on the rest of the world has been very visible.
It is wrong to present this as somehow driven by white supremacy. European supremarcy across the world was driven by military, technological and economic supremacy. Scientific racism was developed relatively late to find justification for the existence of colonial empires.
In many ways scientific racism is a product of democracy and liberalism, because former empires would have had no problems rationalizing their oppression. However Europe was unique in the rest of the world in that ideas of freedom and democracy spread. Ideas which ran completely counter to the exploits Europeans engaged in abroad. These ideas threatened to undermine various European colonial empires. People had to "ivent" reasons why oppression abroad was fine but not locally.
Other nations did not need to invent scientific racism, because oppression of all was simply accepted as the way things worked.
