Friend trouble

I don't have many friends to begin with, and the one I'm currently having a conflict is more of a distant friend I have. This girl takes all AP classes and is failing them, yet still holds the belief that anyone not in an advanced class is not smart. She sits with my group at lunch and a lot of the people at our table only take regents level classes, so it's a bit offensive for her to constantly says such ignorant things. Last week she said anyone with a learning disability should not be allowed to enroll in AP classes, because this one boy who has learning and social disabilities is in a class of hers and is allowed to use a laptop and gets extended time. She sees these tools given to this boy so he can perform on the same level as the rest of the class as 'advantages' and is upset by it. Her discussing this matter at lunch didn't sit well with a lot of my friends and they began voicing their opinion and explaining the opposite side of the matter, how he's not freely handed a laptop with no restrictions and this boy deserves his place in the class. Now this girl is not talking to any of us due to her stubborn attitude and nature of refusing to admit to being incorrect, and I'm really confused. If anyone shouldn't, we be the ones who are mad? She insults our intelligence all the time and spat blatant ignorance at lunch, which we simply were correcting. I want things to go back to how they were, but I don't know how to do that without apologizing to her, and I truly believe in doing so I would be telling her that what she said about this boy was right, and it isn't. Is there anyway I can solve this at all? Everyone at my table would like for her to apologize in person and I really just want things to settle down.

They're hardly advantages if all they're doing is bringing him up to level pegging with everyone else, are they. Okay, so she's grossly insensitive, very narrow-minded, very insecure about herself and needing something she can pin her hopes of being "special" onto, which if anyone even inadvertently and indirectly threatens sends her into Tw*tus Maximus mode... which now, threat-wise, includes you and your group. WHY do you want things to go back to how they were, given how they were unpleasant and offensive to you *and* the rest of your group? Do you not see that this girl has simply met with an opportunity to take off her erstwhile mask, meaning, by wanting things to revert situationally, what you're saying is you want her to put her mask back on, despite you'd now KNOW it was just a mask?

I understand your point of view, and it's partly my fault for not elaborating enough. This girl isn't purposely trying to hurt anyone she's just plain ignorant is all. She comes from a rich background so she really doesn't understand certain values and aspects of life that others attain. Overall, she's a sweet and sociable person, it's just the student side of herself you have to be wary about. I would want to continue being friends with her, I think this fight really does not make a lot of sense because the answer is simple. We have privilege that we take for granted and she held a wrong view that we don't support. Thank you for your response though, it is making me think things over more and I appreciate the advice.
