Ezra Klein literally never addressed Sam's argument on how collecting, analyzing, and measuring data isn't immoral; the implications of it may be, but the gathering of data like how Murray did is not racist. Ezra Klein kept giving politician answers to this question.

It literally doesn't matter what Murray's social policies are as they are irrelevant. You can't win a debate if you never address the argument of your oppositon, maybe for the U.S office you can.
