Lpd, you initially made some interesting points, but unfortunately reverted to spewing BS about pedophilia/homosexuality, meanwhile also just picking and chosing whatever facts serve you best and not responding to anyone trying to have a normal discussion. Instead you just keep repeating that blacks are athletically superior.
First of all, does running ability define athletic superiority? You ignore the technical numbers like pole vault, hammer throw, discus, shot put, javelin throw etc., where whites are superior. Not to mention the plethora of sports where whites are dominant and blacks almost non-existent. In fact, blacks are well-represented in only a limited number of sports: basketball, T&F, baseball, NFL, soccer, what else?
Secondly, you chose to simply ignore the relative percentages of blacks and whites going for a career in sports, which sport they choose and any socio-economic reasons behind it. In the US, for example, The sports I just mentioned are pretty much the only ones where you can make big bucks and become famous (+ tennis/golf/hockey, where you find few successful blacks). Considering the relatively poor average socio-economic status of blacks, it is no surprise that they relatively often choose those sports over other sports. Combine this with the popularity of particular sports among certain races and you have most of the reasons.
E.g. in Kenya/Ethiopia/Jamaica, sports almost exclusively revolves around running. When everybody tries the same sport, obviously big talents will surface.
Same is true the other way around: I'm Dutch and we are the tallest nation in the world, yet we suck at basketball. Why? Don't even believe it's because we lack the athleticism. The sport is simply unpopular and we have no good system/coaches etc, so hardly anyone plays the sport. Likewise, few people choose T&F, since many other sports are far more popular.
