That's news. At Universities here they make up a disproportionate amount of students (ie. a larger percentage of the student body is Asian than would be expected given their percentage of the overall population)...
Tech is brimming with diversity so he can't make a good statistical argument without lumping whites and Asians together as one race. His goal isn't racial diversity, it is the advancement of his race only. Even at the expense of other minorities like Asians.
