There can be only one… at most.
It is impossible to simultaneously understand the theory of evolution and to believe in blank-slate cognitive equality among human groups of different continental origins.
Both propositions—evolution and equality—cannot simultaneously be true. You have to pick one. Choose wisely, because you can’t have both.
Either evolution is a real and ongoing process that has rendered different groups with different mean aptitudes, or we’re all equal—and thus all measurable group disparities in things such as income and intelligence are due to unfairness, hatred, injustice, and flat-out stinking evil.
Yet against all logic and evidence and propelled purely by the smarmiest sort of saccharine emotionality that has ever been shit-sprayed out of human hearts, modern progressives insist that these two fundamentally contradictory belief systems are simultaneously true.
“What sort of person who claims to believe in evolution would deny its fundamental role in shaping human history?”
They insist that evolution is real and that only a dumb hillbilly would not believe in it. But they also insist that evolution had nothing to do with quantifiable disparities between groups in brain size and intelligence, and even if those dumb apelike hillbillies consistently score higher on intelligence tests than your average nonwhite hood rat, well, then, you’re dumb—and evil—for even noticing.
Now, I happen to be skeptical of one and outright reject both the existence and the possibility of the other. But that is an intellectually consistent position. Subscribing to both evolution and equality is intrinsically nonsensical.
