> I'm really tired of having to explain to people that claim to have studied this exact thing why it's not as simple as white people vs everyone else.

Isn't it though? Look at the race numbers for prison, school quality, poverty, profession, representation in media, etc. Even when you control for everything else (especially socioeconomic status; people love to argue that being poor and white is just as hard but hey, racism is still something that poor Black people have to deal with that poor white people don't) race is a huge, dominating factor.
