There are ads all over for the upcoming Baseball World Classic- the real "World Championship," so to speak. Generally, players from a specific country (Mexico, Colombia, etc.) play for that country even if they play in the US the rest of the time; countries with less native players (Canada, Panama, etc.) can reach a bit further- say, American players who are children of Panamanians.
Anyway, the ads show a specific player in his country's uniform with some rah-rah line. Why any ad in the US should show any player other than an American one (Derek Jeter in this case) is one question; another is why some are in Spanish.
But for sheer offensiveness, you can't beat the statement of the Mexican player: "I'm not just playing for my country. I'm playing for La Raza."
Can you imagine some white player saying "I'm playing for my race"?
Oh, and that assumes a sort of uniformity among all the peoples of Latin America. Trust me, they can't stand each other- country against country, and race against race within countries. But let's all play for "La Raza," eh?
