Sounds more like you’re fresh off the boat. All Chinese (Taiwanese) divide the world into “Chinese” and “foreigners”. Most foreigners who live in Taiwan for any length of time pick up the terminology. I don’t see anything weird about it.
There’s a difference between not discriminating on the basis of differences (i.e., thinking that they don’t really matter, although they do exist) and completely ignoring them. The first is possible, the second is really against human nature.
For Bri: I agree about attrition and its problems. I think what I find interesting is how few long-timers I’ve met! Maybe we just get into ruts and go to the same places and see the same people (or the new crop of the year). I mean, I hear lots of people on ORIENTED who’ve been here for a good many years. Had no idea. At least now I only feel like half a freak.
