Suppose I have 1000 people from community and 10 out of them are gender minorities. I then have 5 projects, each with 10 members on board committee, and I want a representative of gender minority in each of them. And I choose hard workers based on merit, the best of the best.
In such case I will be choosing 9*5 = 45 people out of 1000, and specifically I add 1*5 = 5 people out of those 10.
So the board committees will have 45 members each with (worst case) 955/1000 = 95.5% percentile performance, and additionally 5 members of gender minorities, each with mediocre 5/10 = 50% performance.
The gender minorities will perform worse, because we specifically singled them out of the crowd. This is not how you improve diversity.
I think you are right here. By cherry-picking gender minorities we sow a dissent and we underline their "otherness" from everyone else.
I am from an ethnic minority myself, and somehow people perceive us as maniacs and killers, try to burn our houses and fire us from work. Often it's the same people who preach equality and diversity. Somehow in my case they don't care about "empowerment" or "representation" at all. And somehow, the only place I feel comfortable is 4chan, where no one gives a damn who you are, and everyone's racist and sexist. To everyone else. Equally.
