I firmly believe that all human races can be divide between human and subhuman
What kind of races are subhuman?
There are very low human races, I can give you an example
Just because someone is a different culture or race doesn't make them subhuman. Thinking like this will lead them to believe you are racist.
It's not racism, it's subhumanism. I don't want people like this to be in the same place as you.
To view a race as negative based off misguided ideals is racism regardless of how you try to dress it up. You might be better off learning more about these cultures before you find yourself among other racists.
