> The report cited in the article isn't as clear on their distinction and in some cases the numbers indicate that the comparisons are among feeder, in-state high schools; and others are general enough that the lack of detail is concerning as the study leaves out the total population and only provides percentages.

You can look at the data[1] yourself. It's clear that of in-state students enrolling in UCs (not international), Asian Americans make up 36% of enrollees and white Americans make up 20% of enrollees (indeed "underrepresented"). It seems like you are leading on with your comments that it is maybe OK to cut down on Asian representation because most of those students are probably international anyway (which I also don't agree with), but the data clearly shows that such a cut to Asian representation would harm Asian Americans as well.
