Disparities do not tell you anything without first looking at behavior. Looking at disparities without first examining the actual behavior is pointless. If you want to get into the various causes of the behavior, I'm more than willing to have that discussion. However, you first have to acknowledge disparities in actual behavior do exist.
If I told you drownings increase with the sales of ice cream, would you assume ice cream causes drownings. You're part of a very large group that allows your own biases to blind you from obvious truths and realities. You are part of the problem. Hold people accountable for their behavior, and stop blaming the invisible boogieman.
Racism exists, and it always will. People judging and treating people poorly for a countless number of reasons has always taken place, and it will be taking place well after you and I are gone. People will hate others because they are black, because they are white, fat, skinny, smart, dumb, rich, poor, smelly, pleasant smelling, tall, short, wear glasses, don't wear glasses, etc., and they always will. Get over it.
