What did satchel paige prove about baseball fans

Hello!
Satchel Paige was a black pitcher, who attracted fans and filled ballparks when playing in the Negro Leagues for two decades. He is a Hall of Fame Member. 
He proved that baseball fans didn't care about his color, the only thing they cared about was if whether or not he was a good and entertaining player. That helped him to get to play in the Major Leagues in 1948 at 42 years old.
