I dislike being around 90% of blacks because of their behavior, disposition, and attitude, not because of skin color. A lower IQ most certainly is an influence on behavior, disposition and attitude.

With that said even downs syndrome potatoes generally have a good disposition, are mostly well behaved, social, hard workers. They do their best with the limitations that they have. Blacks, not so much. The vast majority are impulsive, violent, and lazy. 

I don't dislike being around most black people because of skin color, facial features, or IQ. I dislike being in the same community as them because of their behavior.
