Don,
I have to disagree. I think everyone uses different parts of themselves to their advantage. Is it any different than the person who takes on golf, drinks beer, talks hockey and hides their heritage to blend into the corporate world when in reality they are completely different at home?
For that matter are you the same person you present at work as you are at home?
I can also see Kacy's point I mean when was the last time someone said "oh she's half white?" usually it's the nonwhite part that get's highlighted.
People will see the asian part of her and assume she is asian. As for exploiting it she is just stating a fact. That she looks Korean. Is that any different than someone pointing out they are blonde, D cup etc? Appearance is very important when selecting a SP so to leave out a major detail like that would cause problems and possible disappointment.
Perfect example I went to see a MPA once and based on her pics thought she was caucasian blonde and found that she was south american blonde. Still a good time but a let down from what I was expecting. I would have been happier if I had more than the pic to go on.
