I used to believe that but I'm starting to wonder if that's true.
But the reality is that they really don't need to bury the truth forever. They just need to bury it for just long enough to where whites are no longer in a position to resist what is happening.
Race realism could easily be used to justify more affirmative action, handouts, and whatnot. They could say "Whites have all these genetic advantages which is all the more reason why we need to prop up POC to help balance things out."
It would not be in their interest to acknowledge such a thing now but in 50 years when whites are 30% of the population, what harm could it do?
