Dear Victor,
I'm glad that we were able to answer your question and I would like to thank you very much for the additional information. It does not surprise me that the sentence comes from literature of CUNY.
The City University of New York came into existence in 1961, and from its very beginning it has been a university with a different perspective on many, many things. It has sought to differentiate itself from New York University (also located in the city of New York) whenever possible. The rivalry between the two schools is palpable.
I am surprised that the CUNY admissions department would use an adjective such as "aggrieved" and an adverb such as "particularly" in this sentence. They could just as easily have gotten their point across by simply saying "or being a member of an ethnic group." Better yet, had they used the word "minorities" they could have covered a lot more people. However, the phrase that follows ("criteria that are increasingly important at America's elite colleges") seems aimed at the perceived practices of other universities. Gee - I wonder which one? They are often quite silly, these rivalries between schools. But it should not be forgotten that these institutions are seeking excellent students just as large corporations seek new, reliable clients. They both need both to stay alive.
Thanks again,
John
