Reducing fascism to amygdala size is idealist pseudoscience (in the vein of nazi race science), biology does not dictate politics. Material conditions drive history. Fascism emerges when capitalist contradictions sharpen and the tendency for the rate of profit to fall creates crisis. The bourgeoisie faces two paths. Either socialist revolution or they turn imperialist violence inward to preserve accumulation. The Nazis suppressed the left to protect industrial capital. Krupp and IG Farben did not care about conservative values but cared about markets and crushing unions. Calling it National Socialism was a tactic to co-opt worker sentiment while serving monopoly capital. Fear is merely a symptom, the disease is capitalism. When accumulation stalls the mask comes off, focus on who owns the means of production not brain scans.
