While McGregor threatened to bury Mayweather in the desert for saying that racism exist in media, Mayweather calmly doubles down on his point while saying he has nothing against McGregor.
Even if you don’t like the messenger, the message is valid.
Throughout the history of sports confident (some would say cocky or arrogant) white athletes are praised while black athletes who act the same are cast as the villains.
McGregor can talk about beheading opponents and no one cares. It has nothing to do with what the Irish has been through as a people. In 2016 he is just able to get that pass because of the color of his skin. If people don’t believe that is true, they are just being naïve.
