This is a good bumper sticker, but it's mostly naive about how humans and biases work. Throughout sports there is significant under representation of minorities in leadership positions. Coaches, administrators, front office, and any other example you want to give. Professional or Ammy. This isn't unique to baseball (or even sports) but is a real thing. The sentiment you express would be a great one to have in some utopia in which people truly did hire the best person for the job, but in reality that isn't the case for a number of reasons. The best, maybe only, solution to that problem is to call attention to it so people are consciously aware of their biases and we can start to change that reality. It's especially important for a sport that has an ever diminishing player base of black players and fans. Baseball hides behind profit margins to ignore deep systemic problems that are threatening to push it into a niche category while most of the 50 year old white dudes who make up their average fan are still alive to see it. Calling attention to these issues, no matter how unpopular with utopian thinkers, is necessary.
