Maybe you don't care, but people of other ethnicities do care. They want a doctor who looks like them speaks their language, understand their culture. Have you ever read the book The Spirit Catches You and You Fall down? If not, read it.
I'll end my post here. All I can say is medical school is a once-and-a lifetime opportunity, and for one race to be admitted due to their ethnicity is unfair, and I am sure that if a medical school admission officer had one seat left and The choice was between you and another person, and the other applicant was selected because he/she was a certain ethnicity I am sure you will be upset as I am.
No hard feelings. Just a discussion.
