I dont grasp the end game of race denial
 
For one, they try to present race as having no descriptive or informative value, which is wrong. We can talk about differences in racial terms, often do just with regard to different traits and outcomes, and meaning is conveyed. The arguments furnished to defend this, moreover, do not support the idea that race is meaningless and describes nothing but merely that it is arbitrary for a classification (with no better system presented, which says a lot imo).
 
Ultimately, even if we accept race is arbitrary, blacks and whites are still different 'somethings' and we can talk about those differences and determine their origin. This talk would just be better served if it were contextualized better, but true statements which inform people could be made all the same
 
oh wait, the endgame isnt greater understanding but halting the conversation
