No I honestly don't. I also think you may not be as racist as you sound, I think you just don't understand the difference between race and ethnicity. How many 'black African' races do you think there are? Answering this question would help me figure out your understanding of ethnicity vs race.
Can you give some examples of the biological reality you think I'm denying? The Wikipedia article you cited did not support your position that race is biologically significant to health.
You didn't deny that 'yellow' is a race. (Again, I don't believe in races, you seem to) Can you tell me some biological realities that apply to 'yellow' people?
