@Witch_Hunter_Siegfired America's official state religion aside, niggers being more physically capable on average makes them more attractive in basically every sport, so there is some logic to it, until the sport becomes sufficiently complex that brain beats brawn. (Cricket maybe? Everyone calls it gay which is roughly the expected reaction from musclebrains when encountering strategy.)

Even if sportsball were explicitly racist/nationalist, however, it would still be bad because it's a fucking black hole of money for the benefit of a couple hundred people, and entertainment for whoever still watches TV - a class necessarily worth nothing.
If it actually funded itself (just buy more tickets) I'd call it net neutral.
