Looking at De Anza College's ethnic info here,
https://www.collegefactual.com/colleges/de-anza-college/student-life/diversity/ , one can see that Whites are not the largest ethnic gropu at De Anza, but third. The "problem" that Tabia Lee did not see as a problem is that the largest ethnic groups is "Asian". Most De Anza students come from the cities of Cupertino and Sunnyvale, De Anza's area in the De Anza Foothill College District. Guess what ethnic group is the largest in those cities. As for blacks, they are just ~2.5% of De Anza student ... which is actually a bit greater than the cities' demographics.
I'm not trying to bore the snot out of anyone, but my big point is that De Anza's student population reflects the ethnic mix of their part of their district (boundaries drawn in the 60s or 70s). Know nothing about her that wasn't in news articles, my guess is that she saw the district's demographics and the student body demographics, and concluded that De Anza was fairly well balanced. If my guess is somewhere close to correct, kudos to her for being realistic and for not hating Asians and Whites. And for caring more about education than the skin color of who is being educated. That should not be a high standard, but in her career field, well, it's treasonous and got her fired. Evidently De Anza College trustees resent/dislike/ham-sandwich more that 1/3 of the college's students.
