In sports, discussion of genetics(often talked about in terms of "race" because it is easier to visualize) and preformance is talked about. Read this book for a in depth discussion on the topic:
To call someone racist because they called Asians nimble is just taking away the meaning of the word racist.
It's not just the one thing, it's the dozens of posts on similar topics (maybe from several posters) about different groups of people.
I'm a geneticist but I'd be happy to chat with you about it in a different thread.
