why are almost all the sub 10 second runners black?
Why are almost all the best basketball players black?
Why are all the best swimmers white?
Be There,
Somehow after reading this I'm wowed by your intelligence for asking these questions.
But I shouldn't make the same mistake that Vince B. did and be impressed with the intellect of someone just because they agree with me [regarding the topic of Blacks and sprinting speed characteristics].
Your questions are actually completely fair, straightforward ones. What is impressive isn't necessarily the complexity of your questions, but rather - your courage to ask them. It takes some balls to ask questions like this. This topic is NOT socially acceptable, and apparently holding the most obvious position imaginable about race and athleticism is somehow taboo.

Regardless, that's extremely brave of you to even ask that question - especially given that, as far as I am aware, you are pseudonymous on here, rather than anonymous. In other words, some people know who you are, and how to find you.
I'm sure you have heard about people whose jobs have been destroyed due to posting benign stuff on Twitter and elsewhere. So I think it's really cool of you to actually ask those questions. Nice to see some sanity on here.
