"But if you look at all the cases of police shootings in the FBI database and compare the cases of white dudes waving knives at cops vs the sample of black dudes waving knives at cops, the police are N times more likely to shoot and kill the the black dudes."
This study directly contradicts your statement:

Another thing that drives me crazy about these "privilege" discussions is how insanely qualitative and emotion driven they are.
What's the outcome for a white kid born in a trailer park vs. a black kid born in a wealthy suburb? Is class privilege completely nullified by racial privilege, meaning the white kid is likely to earn more than the black kid as an adult? The data doesn't show this, and puts a much heavier weight on class and geography being the bigger barriers.
The result of these emotionally driven discussions is that once again, Americans are focused on race being a primary driver of inequality and distracted away from the much bigger issue of class. It's a very convenient tactic for the corporate elites who own our government and want to prevent real change. Racism is a convenient target, because it allows people to blame a problem whose solution doesn't involve massive overhauls of tax policy to better redistribute the wealth that is accumulating with the .01%.
