Yeah...
Honestly, if black and brown people had their illustrious history "appropriated by whites" as the Afrocentrists claim, then it begs the question of why whites got away with appropriating their history in the first place? Because if nonwhite societies commanded such power and greatness before Europeans arrived, then it shouldn't be so easy for whites shunt them aside and take credit for all the stuff nonwhite societies (supposedly) came up with. Clearly, that's not the case.
(Although, in fairness, there were quite a few non-Europeans—China, Egypt, Persia, the Mongols—who built mighty civilizations long before the Age of Exploration got started. So, if honest historians want Western audiences to start acknowledging them more... then sure, I can get behind that.)
