They truthfully reveal that the psuedoscientific 19th century ideas we refer to as race had no scientific basis. Some people really haven't taken this "truth" well though.

Yes, because it's psuedoscientific nonsense that only distracts from the actual truth.
This current controversy includes the attempts to stop exactly this, with rules saying if you do medical research, and classify people by "race" then you need to explain who made this classification and why. Because a Brazilian looking a photos might put people into different races than an American or Japanese researcher, which might differ from the subjects chosen race, which definately differs from their genetic race, because genetic races don't exist.
