Wasn't Herschel Walker on the US Bobsled team?
Blacks dhave not generally gone for winter sports. There are, of course, exceptions and their presence in the Winter Olypics is exceptional. One or two will empnhasize their rarity more than none at all. Now in the Summer Games blacks pretty much dominate certain competitions. Gumbel, as most liberals, are making the case that black people must be forced to like and participate in the same proportions or higher in every walk of life as Euro-white people. In a real nonregimented world different people have different preferences and different ethnic, religious, gender, etc, will show different preponderences of preferences. This is anathema to liberals.
