I would nearly go as far as to say that boxing is the sport in which race and origin matters least. If you put a truly great fighter in front of boxing fans, they will not judge him by race, colour or creed.

Azumah Nelson is one of the most respected fighters globally. Carlos Monzon is revered as one of the greatest Middleweights ever, despite his fatal flaws. Max Schmeling is commonly perceived as one of the sports finest gentlemen. Pac comes from a country not even known for its boxing and is idolised by the boxing faithful. I don't think race is applicable at all. Its attitude.
