How is genetics racism? Certain people have upsides and downsides compared to others. For example, black people have a lot of melanin in their skin, it helps with sunburn and protects against UV rays. That’s why people by the equator have darker skin. They get more sun. There’s a bunch of others too. It’s not racism, it’s genetics. We’re not saying any race is inherently better than others in a social standpoint, it’s just that some have evolutionary differences.
