It makes sense to me. Now that I look back, it may not need to be verbose but it basically states that the admissions process is discriminatory by nature, NO ONE is a sure bet on any school solely bacause of their stats (as is seen by the 180 scorers being rejected), and that marketing yourself well enough will get you where you want to be, despite any "setbacks" from AA.
But I do respect your comment. 
well this is shorter

.
i dont understand what you mean by "it is discriminatory by nature" how? for whom? against whom?
what's your point that "no one is set?" that someone with a 4.0 and 180 is not 100% assured they will get into yale proves/demonstrates what exactly?
same point here...who cares that "marketing yourself" can help you, what's your point with that?
what does any of this have to do with the issue of "AA" being "fair" or "unfair"?
