Gosh oh hell no. I know a black Ethiopian who holds a doctors degree in engineering. Back in 1971 I sold a home to a black man who was a nuclear engineer. Not all blacks are socially low intelligence sounding. Some like the man you do not like, such as Dr. Ben Carson a good republican are definitely not low intelligence sounding. My heart surgeon is a black doctor and he is one fine person and doctor as far as I can tell.
