"Provide evidence?" That's not how shitposting works. You dropped a pseudoscience link as "evidence" in lieu of making a sound argument yourself, and AC called bullshit on you.
You say this McKinsey research proves that diversity makes companies more profitable. In their own words, it only shows correlation. A deeper study may show that companies become profitable, then corporate culture sets in and they start checking off boxes like "diversity", and the company goes to shit but remains profitable for another decade or more thanks to its monopoly position. That's Google to a T.
