One of the courses I'm taking this semester actually gets into the differences in cultural construction between Thai kathoey and transgender folks in the West. I thought of you when it came up.
Interesting! What did it say? Maybe the cultural construction has something to do with why they're so much more attractive.. but it may also just be the small, slender builds of Thais generally...
Well, we're going to be getting into it more later in the semester, and I'll be sure to keep you posted when we get to that stage, but what Professor Shah's been talking about so far mainly involves the problems of anthropologists from Western countries going to places like Thailand or Indonesia or Africa and running into these phenomena and treating them as if they were the same sorts of phenomena as transgender identity in the West, which is poor and somewhat culturally imperialistic ethnographic practice. It seems that these sorts of presentations and ways of life are more traditionally ingrained in East and Southeast Asia, so I imagine that as such they would have more set modes of presentation associated with them, which might be why you find them generally more attractive (I haven't done enough reading or looking into the subject of kathoey to have an opinion on that particular topic).
