Seriously dude, if you're going to make massive claims such as that, you really really need to back yourself up. Just because you think something is true doesn't mean it is.

You realize that college admissions factors in much more than academic scores, right? They factor in if you've ever been employed, your leadership experience outside of school, your extracurriculars, what they're losing in their graduating class that they need in the new one (a good soccer player, 3 more tuba players, etc). Where is your "evidence" that minorities who are accepted are worse in all of these factors that go into who gets into schools? Do you realize that every top 20 school could let in a class of all valedictorians and chooses not to?
Stop saying what you "think" and start researching. The plural of anecdote is not data. You are privileged to not be "seeing" racism. I don't get harassed on the street, that doesn't mean that I assume it's not a problem for a large portion of women in the United States. You have a really big problem of withdrawing inside your own mind, and discounting research in favor of your own opinions. If you only care about your own opinions, then you might as well stop posting.
