If you want to argue that racial diversity is important for your 'elite' universities, that's fine. I can't argue with that since it's really a matter of opinion.
However, if you argue that Asians as a group do not have leadership qualities, diverse extracurriculars, or do anything besides study, you're really just promoting more stereotypical views towards Asians.
I'm Asian, I want to an Ivy League. I played football and basketball in high school. I also took Piano, scored a 1500+/1600 on SATs, and I love snowboarding, riding my motorcycle, and skeet shooting. So I don't believe I fall into any single category.
Yes there are many Asians who study a tremendous amount who love badminton, there are also plenty who enjoy football, snowboarding, and other, more strenuous activities. I'm also sure plenty of you here would be categorically "Asian" purely based off your interests and habits. By saying that colleges refute Asians due to their strong focus on academics is really missing the issue. We're not all the same despite what the Tiger Moms out there would suggest. And I strongly do support a blind college admissions process where race, sex, religion, income, etc wasn't a factor.
