I call bullshit. My best buddy hangs out exclusively with Koreans and Japanese and I have never seen any group of people as obsessed with race and "where are you from" as much as LA Asians. Any discussion about someone starts with name, and within the same breath, nationality, and within the next breath, arguing about nationality. "So I was hanging out with Joe - " "Isn't he Korean?" "Japanese." "I thought he was Korean." "You're thinking of Ted." "No, Ted's Vietnamese." "Anyway, I was hanging out with Joe, and Sandra came by." "Isn't she Laotian?" "Cambodian." Latin Americans don't do this, except to establish that they are HOLY FUCK NOT MEXICAN. Unless they are Mexican, in which case fuck you. White people? Polite white people, at least, have long since learned not to ask... but for fuck's sake, let it go. The only people who give a shit are you... and racists.
