I think what the article is trying to tell us is that there are certain things we do or say that might be a result of feeling superior to another's race or feeling surprised that a person from that particular race was able to do that. You are not being a racist per say, but you have never seen a person of that race managing to accomplish something like that.
Perhaps if a person from a
pygmy background says that he/she or their child is a runaway model, you'd be surprised. I know I will. Don't know about you.
It's like the time when @
Mane said he is 6'4' and I was surprised and if he ever tells me he is financially intelligent I wouldn't be surprised. I didn't mean ill will, and I wasn't being condescending. However, it is possible I was surprised because deep down inside I didn't think a person from his race is capable of doing that/being that tall and THAT IS KINDA :
