I don't know about Mayweather. I mean, that was definitely the case back when there was always a next great white hype being promoted forward and the country watched Friday Night Fights, but it seems like most white ppl have given up having a white contender and this is probably why the sport isn't as popular to the large masses as before. White ppl have seemed to move to MMA, where, guess what, there are white ppl participating and it is popular as crap. I guess, in short, I am saying that the color thing def seems to matter, but I don't think it is about seeing the black guy lose in boxing these days.
Also, I like about half of Kanye's stuff because it is good hip hop. My Beautiful Dark Twisted Fantasy is ridic good.
