Well statistics tells us two things:
1. Yes, minorities and women are underrepresented in the body of students pursuing tech careers.
2. That discrepancy does not explain the wider discrepancy found in tech employment.
Everyone can take and pick bits of statistics to make up faux points (specially when they do not like the actual picture that comes when we use statistical data as objectively as possible.)
I don't agree with point 2, but we're just arguing opinions currently without data.
As soon as you start actively seeking candidates based on underrepresented classes, you're practicing reverse discrimination in the name of "diversity".
