Different races doesn’t mean different species. We are all human, and behaviours associated with being human is universal across the races. The good and the bad.
Imagine having access to thousands of years of documented global human history and thinking there is such a thing as “white behaviour”.
Do you know what the North American tribes were doing to each other before Europeans showed up?
Do you know what the empires of the South Americas were up to?
Who do you think built the pyramids?
What about the Ottoman Empire, or the dynasties of China? How Islam came to be. Or the Persian Empire?
It’s clear you haven’t accessed any of that information OP. Point to somewhere on the globe at random and pick up a book and read. If you do that often enough, you’ll start to see the same patterns of behaviour, repeated over millennia, with mixed successes and carried out on various scales. When humans have the capabilities, they will do terrible things. That isn’t isolated to one race, it is proven throughout our history.
It isn’t that it’s a controversial thing to discuss, it’s just completely ignorant, at best. A bit like choosing not to engage in a conversation with a flat earther.
