I've always liked Kate Beckinsale. She's only a quarter Chinese. Does she still count?
On the subject of whether Asia and oriental cover the same geographic area. Yes, they are the same thing. Israel, turkey and so on are Asia.
Caucasian is a word that really bugs me. People always use it to mean Northern European. You know the Viking types. The word represents all the people's descended from the Caucus mountains. It includes northern europeans, southern Europeans, the majority of the middle east. Yes Arabs are Caucasian. Jewish people. Probably a few others I can't think of. But it encompasses more ethnic groups than the British, French and Dutch. Let's face it that's who the majority of the group referred to as 'white' in north america and other colonies such as Australia, South Africa and New Zealand are.
I always find it a bit odd that people on the states make a distinction between White and Spanish. What's that about?
People use words like Asian, Oriental, European and such as though your talking about a specific group of people but the areas are just too large for that.
Anyway, enough of my withering.
Japanese ladies have always been the ones I find the most attractive.
