A lot of people who are now following me are not caught up on the basics of the black-white IQ gap.
In the 90s, there was a study that adopted little kids out to white homes. The kids were black, mixed, and white. The blacks were 15 points below the whites and the mixed kids…

Leftism may be physically linked to an atrophied amygdala, related to mutational load in the DNA.
Leftists have significantly smaller amygdalas, the "fear organ" of the brain.
This can explain why they use "phobic" as a slur and have no stress response toward mass immigration.

Here's why this actually happens.
High IQ is correlated positively with paternal age and therefore mutational load in a simple regression. This means higher IQ people, who mate assortatively, breed at later ages, producing more mutated offspring.
Older paternal age causally…
