Giving black people and women more resources and outreach, and programs to specifically address some of the challenges they will face, is not discrimination.
We don't have ERGs for white engineers because, simply put, white engineers do not face any structured disadvantages in the work place. There's just nothing to talk about there. That's why we have ERGs for gay individuals, and women engineers, and black engineers. Because they face unique challenges in the workplace and education and those spaces give them the opportunity to talk about that.
If you want those programs for white people, that already exists - that's called the workplace. It's very hard to claim a minority position when you're so obviously in the vast majority.
