, A person's gender or hair color does not determine their intelligence. I really HATE "DUMB BLOND" jokes! Hopefully I misunderstood your inputs and that was not what you were saying. If I did misunderstand, I do apologize; but if not, male-female-brunettes-Asians-African Americans-Caucasians, etc.. are not parallel comparisons to dumb, smart, intelligent, etc. It depends on the person.
