I read a study saying that racism is a learned behavior.
That is only partially true. We do have an instinct to organize ourselves into small groups, and to regard those that don't quite smell like us[footnote]...or look like us, or worship the same gods as we do...[/footnote] as outsiders, and possibly enemies (whose villages we raid and women we steal). Most of the time, we find socially acceptable ways to do this, churches, schools and sports teams presenting excellent examples of ways we categorize ourselves so that our personal tribe is smaller than an entire state.
But children grow up looking at the people around them. The ones with whom they interact are imprinted as part of their acceptable range of
us, whereas those who don't fit into that gamut become categorized as
them. So an urban family who is friendly with neighbors who are differently pigmented, or speak different languages or who is headed by a same-sex couple will, themselves, raise kids who are accustomed to a polyfaceted community. Contrast to a family who lives in an isolated town where everyone is the same color, speaks with the same dialect and goes to the same church. Kids from that family will have a harder time adjusting to someplace where people are less homogenous.
Humans also go to great lengths to justify our categorizations of others such as calling dark-skinned people
primitive or women
emotional[footnote]Indeed, the world's intelligentsia emerge from all genetic sources and ethnic groups, and men are just as emotional, only really tending to
act sooner and
confer less.[/footnote] and these justifications are passed on by parents and teachers, to kids, reinforcing racial prejudices, often contrary to peer-reviewed evidence.
