Let's just say that you would put your kids further along the road to success if you used URM sperm for babies than if you gave your kids a top rate education; when the gene for dark skin color comes out, my kid is getting it.
The effect of that thinking is pretty self-evident. Race has no place in America, good or bad, URM's are just hurting everyone by selfishly perpetuating stereotypes. They continue to trash MLK's grave.
That being said, ethnic diversity is real and valuable as long as its identification is by evidenced experience in that diverse environment (i.e. living where you are a minority or experiencing something that your minority typically experiences) and not by checkboxes.
A URM with ethics would not choose URM status on AMCAS or med apps and would instead talk about their URM in an essay or personal statement.
A black kid brought up by rich white parents should not get URM status, IMO, right now they do.
