I would advise fighting the caste system by challenging the commonly held beliefs that white people cannot run or jump at an elite level. The mere existence of Lemaitre, Guliyev, Connaughton, Di Gregorio, Cerutti, Pickering, Unger, Shirvington, Collio, Wariner, Rock, and countless others is proof enough that steroids or not, white people can not only be fast but run with the fastest blacks the earth has ever seen. The "all blacks take steroids" crowd has trouble seeing the big picture. The systematic overlooking of better white athletes in American sports, as well as the many myths about black athletic supremacy created by the media across the globe, is not anywhere near as connected to blacks doing well in shorter sprints as some people here might think. Although a self-fulfilling prophecy is created by many of these myths that discourages whites from maturing and competing in the sprints at an elite level, the fact that a sport exists for the primary purpose of simply running fast in a straigt line, in which whites are still competitive, is proof of the ludicracy of the caste system in American football and other sports. No other race comes close to the all-around athleticism of whites. It's simple. There's even a decathlon world record to prove it.
