Again; 'tis SOOOO un-surprised I am!!! And more than that: it's about making sure that the White Men for whom the system hath a preference are also Members of the Club. If even a pale male is judged 'un-clubbable', zere are VAYSS to nudge him out!
I know this from firsthand over two generations: my dad's and my own!
Rewarding whiteness is baseline; rewarding White Maleness is the ultimate objective!
