you're pretty ignorant and stupid. Let me go over this and prove you wrong. First, jeremy wariner won the 400m sprint last year. He is white. Second, Reese Hoffa is the leading shotputter in the world right now and hes black. Third, the US bball team gets killed because they don't play as a team. Fourth, I don't even know what event sword is. Fencing? Try naming the events correctly. Fifth, China and Russia are good at gymnastics, but you forgot about Romania, the US, and all other countries that are good too.
Your last part is the worst. How is a guy throwing something or "running right in front of him jumping over things" (what does that even mean, makes no sense, speak english correctly please) any different from a guy skiing down a hill? In skiing, people must execute tricks with perfect technique and style to do their best. Track and field is the same exact thing in a different venue. The best athletes in the world have to execute their events and techniques perfectly or else they will not win. So in conclusion, you're an idiot
