<p>To get back to the OP's question: no, you shouldn't feel guilty about going to MIT as an Affirmative Action applicant. Even though I see lots of flaws with Affirmative Action, the admissions rulebook at most colleges right now includes it, so you're just making the most of an imperfect regulation. But realistically, you can probably expect to have some people being skeptical about your degree the rest of your life.</p>
