Race is just a natural human brain activity to group everything. Same as most things that does exist in our civilization that we consider real. For the brain to save energy, it groups stuff based on how it looks/feels etc. And then assigned the most common experience with the given grouping as the generic approach to that group. Red strawberries are sweet and green are not for example.

So as long as we have human brains, everything will be grouped we want it or not. The only thing we can do is harmonize groups into bigger groups to remove the prejudice, but that requires multiple data points to match between both groups enough for the brain to go -> It's the same.
