I appreciate it, thank you!
Because Asian is general, implies no difference between the many different peoples from Asia, and implies that we are all the same . It's like saying Latin or Caucasian instead of bothering to find out what country someone's from. Also, saying it all the time implies that there's nothing else noteworthy about her and is reductive at best and fetishistic at worst. Like saying a white guy does things whitely all the time instead of letting him do things because he's himself .
