That's not it, bubba. Your post itself described how those two situations are different.
Lio was asked many times to carry bags and do things to "earn respect". Black did on his own and was told he didn't need to.
Neither are wrong per se, and Lio doesn't even believe that the WWE is a racist company. But asking a then 23 year old African american man to carry bags for grown ass men, especially white men, with that reasoning surely could lead to uncomfortable situations.
Like, it took him two years AFTER trying to solve the problem internally, and even then maintaining the identities private, to make this situation public. He may have been immature in other situations but this wasn't one of them.
