Hate and racism are learned. Now, if you want to say that selfishness and fear are not, that I could be more in agreement with. Those can easily morph into hate and racism. But I've yet to see a child just "naturally" be racist or filled with hate. Perhaps the seeds of these evils are in everyone, but whether they grow will depend on whether they're watered by those around them.
Except there's a whole body of in-group out-group research on children that suggests the opposite. They notice differences and react to them, race specifically. You might argue that the reasons used to revile other races are learned, but the distrust is quite natural and could logically seek its own justification if not taught otherwise.
Which suggests btw, the opposite, that they must be taught not to distrust those that look differently, much like they must taught not to be selfish.
