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?
Said the guy pretending to not understand basic terms, whether or not he agrees. (You disagreeing with those terms' practical existence is the example)
Mate, no. I understand the practical existence of race (well... to the extent a nonracialized person can) what I'm talking about is the expert consensus that: the matter of where the boundaries between races get drawn is determined by social factors, not biological.
The question of whether an ethnicity was (and is) 'white' or not was a political question, not a biological one.
