I suspect a part of it is ignorance: "all Asians are the same" sort of thing, so everyone gets lumped into a singular category.

But I also suspect that it has something to do with the lack of content. If I were to create a category on my link list for "Indian Guys" I doubt I'd have much in it. If I create a category called "Asian Guys" then it would at least have some content list in it.

It's like of like bears, if you break them down into muscle bears, daddy bears, polar bears, chubby bears, bear cubs, you could end up with five sparsely populated categories, but if you just create "Bears" at least you get the surfer going in the right direction.
