Equality of outcome.  Should we insist on more boxing champions being white?

No... Boxing is less about skin colour and more about upbringing. Those from poverty stricken backgrounds tend to make the best fighters as they have the most to gain by getting great, also they tend to grow up fighting which gives them more experience in taking a punch.

Then it comes down to the individuals ability to learn, hardwork, dedication and physical gifts.

Fury is a white guy who grew up in a gypsy background,  not the richest and grew up fighting. His dedication to becoming better, even now has made him the best heavyweight in the world. It's sod all to do with skin colour, it's all about the attitude of the fighter
