Homogeneity is not normal. But we’ve been conditioned toward homogeneity and non-diversity over the decades by media, exacerbated in 2016 with Fox News crowned the most watched cable network and their all-white men prime time line-up. By pop culture and its lack of diversity in TV, movies, magazines and books. And even down to education design with text books.
This has a dramatic effect on our behaviors, intentional and conscious or not. We live in a world where people with prominent Afrocentric features received longer criminal sentences because of how they look. Where white kids are more likely to be prescribed painkillers than black kids. And where even preschool teachers are conditioned to look to the black students for disruptive behavior.
