If you start saying that racial differences are not a factor in sporting achievement you are opening the door for the White liberal champions of Black atheletes to claim that Blacks would dominate tennis, cycling, equestrian and skiing, etc., if only they didn't suffer from social and cultural discrimination
Only if you believe that blacks are naturally superior athletes. Otherwise, why should I believe they would dominate any sport in excess of their numbers in any given population group?
I *might* cede short sprinting superiority to certain black phenotypes, but even then, without the caste system , slotting, and the social-psychological hurdles white athletes must face and overcome to even believe they *can* compete in sprints, even my concession in that arena is dubious.
And as for black domination of boxing, what with their superior speed, reflexes, arm length, and thick skills, why do they get outjabbed and outboxed by Eastern European fighters? Do the Slavs and Poles and Ukrainians have faster reflexes than their Western European counterparts? And it isn't because there aren't any black men in Europe, there are plenty. Lennox Lewis and Danny Williams ring any bells?
And what of Latino fighters? Do you consider them white or black, racially? There are plenty of lighter skinned Hispanic fighters who dominate the lower weight divisions in boxing.
There may be racial differences that permit some black athletes a slight edge in certain, specific athletic events, but there is NO WAY it is so great as to lead to the percentages of black athletes we see in sports today. And yes, that includes boxing.
