Let's just establish a few things before you get this thread going in earnest:
1. Socioeconomic status is certainly taken into account in medical school admissions. In spite of this, most medical students come from a very high socioeconomic status as wealth is the best predictor of academic success and academic success is still the central factor looked at in medical admissions.
2. Asians are not "punished" for being over represented. They are overrepresented in the medical school population by a factor of 4 and yet don't have significantly higher matriculating averages than Caucasians once one corrects for the high number of Asians living in California. In other words, in spite of their representation there is no evidence of Asians being held to a higher standard than Caucasians in admissions. Bottom line: Asians with strong applications are still getting in, Asians with weak applications are not.
3. A greater proportion of African-American and Latino students have low socioeconomic status than do Asian or Caucasian students. (Remember 1).
4. Most professionals (and nearly all education professionals) understand -- and can cite a dearth of literature that agrees with -- the notion that diversity is intrinsically valuable to education. Do not be fooled by the above poster just because they sound certain of themselves. If you are curious as to how then ask, don't just assume your position to be correct.
5. Nobody deserves a spot because they met some level of academic benchmarks. At most, you are academically qualified but that does not necessarily mean you are worthy of admission. All applicants who make it into medical school are academically qualified in the sense that even applicants on the "low academic" end of the admissions spectrum pass their boards and earn their MD greater than 90% of the time.
6. Medical schools have missions and goals that data suggests can be better met by selecting for specific types of applicants. This might mean more Latino and African-American students; it could also mean students from rural Mississippi, students from that State, students who are highly adept at scholarly work, lab scientists, etc. Diversity is not one dimensional. No one is arguing that all of the ORMs in medical schools are identical copies of themselves and that only URMs can be diverse.
Now that we have those out of the way, feel free to talk about the perfectly valid and important topics of the types of racial discrimination Asians do face in admissions such as:
A) Having to provide evidence against the implicit but unfounded assumption that highly-performing Asian candidates are somehow socially inept, driven totally by external factors and family, or in other ways "robotic".
B) Facing what may be implicit admissions quotas in medical admissions that do not seem to be equally applied to other ORMs, namely Caucasians.
C) Facing the implicit and unfounded assumption that they do not experience racism.
etc.
