Assume racists are correct...

I don't know what 'empirically superior' means. There are not a lot of white guys winning the 100 yard dash, but overall the whole population of whites and blacks the difference in this and other areas are not great and most importantly individually people vary greatly. That's where the case for racism really falls apart. Individually there is so much variation between people within populations that racism totally ignores that and debunks itself. That's the intelligent way to confront racism. Not to pretend that there are no genetic differences between population areas, or to just dismiss it outright. That leaves racists feeling like we aren't willing to confront them or challenge them.
