Lebron's struggles as a black man in America are a huge part of his success story. Not just that he's excellent at what he does. Pretending that race doesn't exist does not actually work in practice. LeBron himself will tell you that.
Exactly how did he struggle as a basketball player? White Men Can't Jump was a 90s movie, and back in the 80s, Bird was a the great white hope as redneck from Indiana, because the top players were mostly black, and Bird was even called out as unathletic by Dennis Rodman and Isaiah Thomas after he won a playoff game over them in Detroit.
Selling his body? Are you serious?
He wouldn't have been able to become a cop, a nurse, a clerk, a financial professional or any of the other thousands of professions that black people in the midwest find themselves in?
LeBron's struggles seem less part of his success story and more part of a self-penned "rags to riches" legend.
I would even say that being black was an advantage, and gave him great genetics that he took to the next level with discipline.
Being Jewish was a great advantage to Einstein, and gave him great genetics that he took to the next level with discipline.
Being French was a great advantage to Joan of Arc, and gave her great genetics that she took to the next level with dedication.
LeBron may have great genetics. But if he does, it's because of his parents and luck, not his race per se. Otherwise everyone who is black would have a genetic advantage that they could take to the next level with discipline.
It is racist as hell to attribute to race what are personal qualities. Other than, perhaps, traits that only certain races possess, such as the ability to breath at high elevations without taking weeks to adapt to the conditions.
