He already knows the truth. Dr. Lefkowitz tried to debate Afrocentrism and seemed genuinely shaken that she wasn't treated like a scholar, that her opponents and their disciples are fond of poisoning the well and other ad hominem attacks and that they do not follow traditional scholarly standards of evidence. They also seemed to believe that being African-American and going to Egypt in itself gives one authority on Afrocentrism not available to whites. Afrocentrists are already entrenched in our schools and universities. They are part of a growing, not diminishing, movement.
White people have their truth and Afrocentrists have their truth.
Fairness demands that the theory of evolution and the theory of creationism should be taught to our children. Theories aren't absolutely certain, so they're epistemologically equal. Truths aren't absolutely certain or objective, so they're epistemologically equal. The errors behind these beliefs are distinct, however. Furthermore, they are wrong in assuming that some theories are not better than others.
