I think you're also missing the point.
If a company is factoring in a person's race and/or sex when going through resumes, then there is already something wrong with the way that company is handling its hiring practices. Any decent business would vet potential candidates by the credentials within their resumes and impressions made during interviews, not their gender or race.
I'm not missing the point at all. The point is that in most companies there IS something wrong with the hiring practices. Not out of some malicious objective setting or purposefully, but often out of a focus on the current company structure, old selection practices based on names, specific universities or schools and places of birth. Many companies miss many brilliant people because -without doing it really purposefully- they focus on specific resume patterns that exclude certain groups.
That is what this is about. It is not about adding additional races and genders to any company to make it represent society. It is about making sure that all have a similar chance, where they previous didn't.
