Racism is a behavior. Nothing else you mentioned is
Precisely. And as such it can be controlled. This is why I reject Julian's pseudoscience about racism being baked into our psyche. There is all kinds of stuff that we could justify if we go far enough back in our genetic history. It simply won't fly today. Behavior is learned.
The very notion that racism is a naturally occurring phenomena is preposterous. Well. Even if there was some truth to the notion (and I do not grant that there is) we overcome far stronger impulses from earliest childhood. He will find no cover in claiming that racism is baked-in.
God is a comedian playing to an audience that is afraid to laugh.
