Yeah the problem with the term 'asian', is it's constantly mislabeled, as it covers such a wide range from what I have seen- from Korea to freakin' India to Persia...and now Cuba. If you don't know the nationality, just slap 'asian' on there.
Personally, I think that 'asian' is more ignorant than 'oriental'. At least with oriental we know we won't be getting some chick who's actually Cuban. I also know east asians who use the term oriental when referring to themselves and they don't think there is anything wrong with it. And I know what its definition is currently, so I don't need a language lesson on it, thanks.
