Bullshit. My face is fairly narrow and I'm still a blatant bigot.
I've noticed a specious presumption in the argument too. It presumes the desire for racism comes from dominance which in turn is a trait of high testosterone. It just seems like more misandric propaganda.
The desire to explicitly state racial beliefs comes reactively from a lack of Volkerhass --- fit with modern cosmopolitanism, really. Most whites are, if anything, cowering away the best they can whilst maintaining some semblance of Aryan values. These would all be traits of a low-testosterone race (well, low body serum testosterone, which simply says the brain is consuming more of it, and contrary to the article's argument that's actually associated
positively with frontal function, what bullshit is this stupid womb-god reading?), which the Europeans are, compared to both blacks and Jews, who have titres 2 and 4 times Whites respectively.
