Two articles (both by Asian-American reporters) on William Hung argue that he is reinforcing Asian-American stereotypes. I’m inclined to agree.

The upshot is that when it comes to virility, Asian men rank somewhere below white women, and for FOBs (“fresh off the boat,” not friends of the ex-president) like William Hung, the reality is much, much lower. At the end of the day, Hung makes us all feel better about ourselves: Men can feel more manly and women are free to act like sluts. For Asian Americans, Hung represents everything we don’t want to be seen as (foreign, nerdish, a joke), and thus his oddball fame reinforces our own happily assimilated identities.

One thing can be said for those who seek to exploit William Hung: He has not been asked to demonstrate any karate moves or threaten the American way of life.
So, where’s the outrage? Even the Asian-American community seems to be taken by Hung.
“As Asian Americans, we look through this racial lens, and we see this guy who embodies all the stereotypes we’re trying to escape from,” said James Hou, a documentary filmmaker who explored Asian-American male sexuality in “Masters of the Pillow.”
