No one is born a racist. That means racism is a learned skill. Like reading and writing.
In toddlers, this can be clearly seen. They make no distinction in skin color when choosing their boyfriends and girlfriends.

Until sooner or later they are reminded by society that someone with a different skin color is' different '.

“People are taught how to hate. If you can learn to hate them, you can also teach them to love each other. Because love naturally fits our human hearts much better than hatred.”

{Nelson}

Racism is not a congenital anomaly
