The truly talented can never rise to the top in this climate. This gives the ruling elite complete control of who gets in and go does not. Yes, whites will get in, and even white males, but not Christian white males or conservative white males.
Forget rising to the top, you'll never get hired in the first place. The state university I teach at requires such loyalty oaths for academic search committees. Non-Leftists will be blocked out of employment from all academia.
