they are historically illiterate and aren't in the know. basically all relevant developed civilizations with the exception of several asian one; have had at the very least an upper class of caucasians as the centerpiece. sometimes it's a higher population core group and not just upper classes. all of the "southern" mena and even indus valley have had these societies with a caste system. they erroneously try to project their hypothetical capacity to be able to even sustain a complex civilization onto the contemporary browns that exist there(post collapse). if that were the case then why have these areas of the world failed to stay relevant or even recover for millenia(or like 500y in case of me). they are littleraly monkeys using a historical revisionist narrative that paints many past civilizations as brown by contemporaries looking to steal their heritage(akin to jews larping as israelites). indians do the same thing pretending they are aryan. the real truth that 90% of even the contemporary archeology/history even let's you know about. it gets even worse when you find out the truth about humanity being much older than what they'd like to admit.
