"In a society where predatory abuse was unacceptable to a extreme degree, very few people who felt that Blacks are inferior would take to harming Blacks."

I guess you're right, but wouldn't creating a society that was free of predatory instincts be even harder than creating one that was free of racism? Predation, in its various forms, seems to be an even more fundamental human drive.

I suspect people will always find reasons to fight. But Think we can find better things to fight about. Maybe even things that eventually lead to a better world.
