My sense is that "racist" isn't the term to use here-- just sort of culturally intolerant or even xenophobic. When he refers to "Us," he's referring white, black, and latin decent (with Team USA being the agreed upon "Us"). If he had made these remarks about another MLB team, no one would think twice about it-- but since it's culture versus culture, it becomes a much larger conversation. I wish he hadn't said it-- only because it does come off as ignorant and silly. I for one, love the image of Kirby circling the base paths with his fist clenched and screaming. Many of the most iconic moments in the history of the sport are the result of "showboating." It's part of the fun. I also welcome those who don't wish to do it-- but let's not ostracize those get excited when something exciting happens.
