What a load of hogwash. “Diversity” has absolutely nothing to do with your chances of success. Hire the best talent to fit your business regardless. Being politically correct with your hires handicaps you the same as being racist with your hires.
Talent is talent. Some have it some don’t. When it comes to particular talents we are not all created equal. If you need a 6' 8" power forward, don’t hire the 5'6" girl because she’s a Buddhist. If you need a professional drummer, don’t hire a pianist because he’s white.
No snowflake, you can’t be anything you want to be, often you have to be born with talent or physical size and no amount of desire or training can compensate.
