We are at a point in society where the majority of us view each other as equals (race, gender, etc.); therefore, we should frown on advantages given to one subset over the other that upsets this balance.
We are getting there...but we are definitely not there yet; not even close. You come from a position where the world is fair and if everyone just puts in their best, we will all be on equal footing...as someone mentioned earlier, just by virtue of your race, you are either automatically advantaged or disadvantaged in some areas (including education)
Let me give you an example... my dad's an Engineer and I actually grew up in the wealthy part of town (i.e. I was the token black dude), hence my high school was predominantly white. Even though I was a nerd, do you know how many times coaches expected me to play sports and when I ended up sucking at it, they wondered what was truly wrong with me... also some students would walk up to me wanting to buy elicit drugs or asked if I knew someone who sold one. There was also the perception that I had to be cool...very far from it.
Someone mentioned earlier that people expected them to be good at math simply because they were Asian American - while this is not racism, it's prejudice because we prejudge someone solely due to their appearance (probably by the hue of their skin). You might say that you don't do it because you weren't raised that way...but what you have to understand is that it has nothing to do with how you were raised, but more of what you as an individual perceived from the society around you. For instance, if I go to the ATM at 9PM and a younger version of me was standing right behind me - I would be a little more apprehensive as a result of what I had perceived growing up. You really have to condition yourself not to see the color of someone's skin, it's not easy but it's the only way you can ensure you treat everyone fairly.
The problem here is that most people assume that they are not like that, when in fact we all are to some degree. My point is that the general perception of a black or Hispanic person is negative... and this negative perception will most likely follow them the rest of their lives whether the become doctors or not. This has profound implications and definitely has a root in why we have fewer medical practitioners coming from the URM group.
ADCOMS simply get more URMs in their school because they try to rectify this situation and also don't want the school to be all whites and asians... they want a little bit of diversity, which I dont flaw them for - afterall they are searching for completeness in all students education experiences.
Of all the threads I see about URM getting undeserved spots in medical schools, I don't think I have ever come across one that talks about the impact of this URM thing on how a brown/black doctor would be perceived. Unless you personally know the doctor and their academic endeavors, you will automatically assume they got where they are as a result of URM status... which is not the case for a lot of URM docs.
