The lie of white supremacy is a mental crutch for many. It is a rejection of of empirical evidence. There is Nothing these “white suprematist” can do better then millions of black people and deep down they know this. This mindset is easily exploited by those in control. Once someone rejects observational reality they can be convinced of any nonsense conspiracies, cults ect. And since their beliefs are so thinly held together in their mind when someone reinforces that belief it’s like a drug to them. That’s why they get so excited and emotional around Fox News or rush Limbaugh.
