Having read the legislation, this is the right move for education. The author of the Slashdot article adding his venom that this suppressing the white non-Hispanic males doesn't help.
The legislation starts out with their problem statement, "The computer science and education grant program, known as8the CS and E program, is created to address Washington's shortage of computer science professionals." Washington state believes they have a shortage, not arguing for or against that belief, but that is the problem statement. Now I suppose Washington state has looked at their CS classroom demographics and see that females, low-income, and minority students make up a small percentage of CS academia. I guess that Washington state assumes that if they are gaining maximum participation from males, high income, and majority students, yet still have a shortfall, then it makes total sense to offer grants to tap into the student demographics under represented. Meaning CS naturally taps into one pool of resources and now it's time to make an effort to tap into another pool of resources to help fulfill/solve the stated problem.
This is not about repressing the white male and elevating women, minority, and low income. It's seeking to incentivize educators to reach beyond what is easy to get in the classroom and see if they can get others into CS.
