The two don't follow, at all. Lets replace this statement, and make it about the NBA.
"If you truly believe people are equal and deserving of equal treatment then you must see a game where black men hold the vast majority of positions as a failure of the game".
If the NBA example should be laughed at, why shouldn't the opposite? Neanderthals don't exist anymore, but homo sapiens do, despite very little relative advantage to us. Small differences in averages between groups will lead to dramatically different results. For the best example of all, see casinos (advantage: 2-4%) versus gamblers.
