This statement is dumber than the one suggesting managers should be able to change the batting order in the 9th inning. For 1, racial demographics should be irrelevant. Teams are going to draft/sign whoever they think gives them the best chance to win, regardless of race/nationality. Why it would really matter to a fan, I can't fathom. 2nd, even if the racial demographics were relevant, your statement is statistically incorrect. As of 2017, the number of black players was the lowest it's been in over 25 years (less than 8%). Hispanic was around 32ish% and white/caucasian/whatever accounting for nearly 60% of players.

So, your statement was both ignorant AND stupid. Congrats, that's a feat.
