I registered an account to just reply to this.
I've noticed a trend on this forum (and in real life) of how quick Asians are to tear each other down. With other minority groups, there's more of ... solidarity. A hispanic, black, or LBGT person expressing a desire for "diversity" would never be met with scorn from his fellows. This person is obviously an immigrant and would like to mingle with other Asians who share the same values. I see nothing wrong with that. How would it be received if you called out a lesbian yearning for more diversity by saying, "Hah! All you want is more LBGTs! You're a phony!". Obviously we all know what the word diversity has been co-opted to mean concerning minorities.
I question why your reply was filled with such vitriol and condescension. My guess is that you're using him as a punching bag for your own unresolved issues with Asian immigrant values, but I digress.
I also disagree with your assessment that he has "deep-seated issues". Really, as someone who is Asian yourself I'm honestly shocked at your lack of sympathy. Asian men are stereotyped as effeminate, short, submissive drones regularly by popular culture. They're continually pigeon-holed into archetypes. You don't think these bleed over into prejudices on an individual level? Since you're a medical student, I bet you like data:

Luckily, I've never felt the degree of alienation that he does. I was born here, but my immigrant story is likely the same as his. My heart breaks when I remember my mother being turned away from job after job because she spoke English with an accent, or when I hear the racism my father still experiences to his day in his job. And I live in a coastal state. Of course my parents would've wanted an Asian community around them. Every immigrant wants to feel less alone.
Great insinuation that Korean women will only be shallowly interested in his status, by the way. Let's disregard the whole shared cultural experience thing and try to take him down another peg, eh? No way could a woman find comfort in sharing cuisine, language, parental expectations, values, or hobbies with him - traits that I'm sure align more closely in two people from Korea than from some other country - right? Nope, she's only after your money!
Seriously?
Calling him a dolt for seeking acceptance is counterproductive. What he expresses may not be completely political correct, but is a common sentiment I hear from immigrants, including non-asians - and it comes from an earnest desire to succeed in a new, unfamiliar country.
But I suppose all he has to do is "be more awesome", right? Great counseling there, MSwhatever.
