Is it racist to recognise the differing strengths and weaknesses of different races of human beings?
Kenyans are generally supreme at long distance running. Jamaicans are generally supreme at sprinting.
Afro Americans are generally bigger and stronger than other races.
Indians / Pakistanis are as a race, generally more intelligent than white west European people.
Well documented.
So just stating the facts, is it racist? Should we turn a blind eye in the interest of Political Correctness?
Lots of people seem to make sweeping generalisations all the time.
May be better, if you are saying that these are well-documented, to provide said documents, so that we can judge these claims for ourselves. I suspect that there is a grain of truth to some of these but there differences are probably exaggerated, and perhaps not even that statistically significant.
Stating the facts isn't racist. Nothing wrong with saying that very few white men have run 100 metres in sub-10 seconds (just one, I think) or that many of the best long-distances runners are Kenyan and Ethiopian.
If you split any group into arbitrary halves there are bound to be differences between and within each subgroup. This say nothing with regards to the value of each individual . . . in either subgroup.
Not aware of the literature, but do know that "affirmative action" is necessary to get disadvantaged minorities (i.e. black Americans) get into Ivy League colleges, while the opposite of "affirmative action" (whatever that is call - presumably not "prejudice", or "discrimination") is required to ensure that otherfar smaller disadvantaged minorities (this includes Chinese, Japanese, Korean and Vietnamese) don't get too many places in such universities.
