I think the term "model minority" referred to Asians because, it was perceived that despite coming here often with nothing and having to learn a new language (even a new alphabet) they managed to out achieve everyone else - even whites who were always assumed to have the advantage over everyone.
This has caused a lot of resentment. Here in Northern Virginia, Thomas Jefferson High School - a school for gifted students in science and technology (where an entrance exam was required) was overwhelmingly Asian - well in excess of their overall representation in the population. Apparently, this was unacceptable under DEI philosophy.
Havard also decided they had too many Asians.
Suddenly, working hard to achieve is unfair somehow.
I think the anger generated by Asians - as a group - doing better than other minorities (and even whites) is that if they can do it, why can't others?
So, in many ways, playing into the "model minority" may anger people more than win them over.
