Here's an interesting article about seven Asian-American stereotypes that the author says aren't true, including the belief that Asian-Americans can't play sports but all know martial arts.
Unfortunately, it doesn't help her case that the list of Asian-American pro baseball players she uses (Ichiro Suzuki, Hideo Nomo, Hideki Matsui, Byung-Hyun Kim, and Kaduhiro Sasaki) are actually all foreign players, so Asian, not Asian-American.
But whatever, apart from that, it's a good refutation of the stereotypes. I thought the "Asian F" (i.e., a grade of a B) was especially hilarious. (Been there, endured that.)
