I also don't think "quotas" are a good solution, e.g., "Hire one more Mexican woman and we're good!" But acknowledging some statistical realities and taking a close look at what got you there isn't a bad thing.
You make it sound like the problem would go away if we'd just stop talking about it. That's not a solution; that's just sweeping it under the rug.
The problem ises some people know that they can discriminate against people based on skin color. They learned that certain groups had certain stereotypes. They learned these "facts" because people around them reinforced that these groups were different by talking about how the groups were different.
Talking about race is only going to beget more racism at this point.
The choices you make affect real _people_--not institutions; hiring someone over someone else based on some relatively arbitrary superficial trait--thinking that you know that person and what they've lived through--has serious effects on that individual--not an institution. But you choose to make those choices, because you perpetually believe you know things that you do not.
