Who is OP?
BTW, it's about the structure of the brain, not the color of the skin.
Yes, OP stands for original poster, that is you.
Well, I don't know, you said there is fear of being called racist. That with all the stereotypes sometimes attributed to black people, made it seem to me like you are talking about races. You reply now still doesn't claim it is not about race, just claims it is not about a color of the skin.
So for clarity reasons, this is the point correct?
You believe that these people belonging to a different race also belong to a different species, that they are not human, correct?
It just seems to me like there is much ambiguity in this post.
