I would counter that by pointing out that the actual racist/sexist hiring practices are what led to the imbalance in diversity in the tech field, and I'm not excluding anyone due to their race/sex (no quotas, no "I won't hire white guys" etc) but for every job post if there are 200 applicants, 10 worth interviewing and 3 that I am seriously considering, it becomes a judgement call who I want on my team but I I do not use race or sex as the deciding factor
