And they were only admitted because of AA.

After all expecting a college student to be able to read is totally unreasonable.
You seem to be reading a whole bunch of stuff in there that isn’t in the article.
However, I can factually state that a large number of Latino college students learned English as a second language, and while literate are not necessarily as literate in English as natural born Americans raised with English. It doesn’t mean that they are illegal aliens, or even naturalized citizens, just that their household language when growing up was Spanish.
A literate American who speaks German would be similarly disadvantaged in studying Goethe in Germany. It doesn’t mean he is inferior in any way, just that he might miss much of the subtlety of Goethe that Germans would culturally notice.
