This is a nice article, but it does have some parts that seem off base. First you can walk into any chinese grocery store (in america) and get 20 kinds of tofu, thats really not an issue, and chinese restaurants (in chinatown) will sell many kinds of tofu.
The other is that the author makes the mistake of over emphasizing the vegetarianism aspect (which i think some comments here also are). Many chinese dishes with tofu flavor them with meat. Outside of a temple, the vegetarian aspect isnt really important, tofu is just another dish. Tofus attachment with being a meat replacement or a vegetarian food is the major reason its not eaten more by americans.
