Bloodlines. That's what this is about; it's what it's always been about with (((them))).
Could you imagine favored treatment only to those whose genes you'd like to promote? Only to those that're part of the approved bloodline? It's a new royalty and caste system.
Not only do they know your genetics, they know your proclivities. Approved bloodline that steps out of line? No home/breeding rights/food.
They're trying to push and breed man the way they see fit.
