But how do you know the OP was refering to US nationals of Asian heritage? Perhaps they were refering to Korean tourists and using the pejorative 'Asian'? In which case her comment would not be 'disrespectful', as you seem ready to assume. If she asked the same about, say, Russians and Aeroflot would people be so sensitive?
