You know why there is still such a term as racism? Because people refuse to be color blind. It's just pigment and melanin at the end. We want a better world but we're still stuck on the mindset that we're different because our skin shines different. You can try writing on equality, use your own way to let the world know that humans should just be seen as humans. Do you realize that no matter what color an alien is, they'd still just be aliens to us? We could use that same logic to make us better people.
