Um no. No one should have to justify the spot in an organization based on their culture, race, sexual orientation or gender. I think your scenario illustrates how ridiculous caring intensely about cultural background is for hiring situations. Wouldn't diversity of hobbies, or college education backgrounds be just as valid? Business should be about business, not crafting the perfect society. If you're a good person and a good fit for the role then you're a good fit.
I believe diversity is a admiral goal for an organization. I just don't think DEI policies give enough benefits to the groups they want to protect to be worth the negative second order effects.
Inefficient and poorly managed companies might. I think it's obvious that women are often more competent then their peers, and their workplace value is obvious to anyone in leadership positions.
