I cannot think like a black man or woman, I cannot experience discrimination and hate directed at LGBTQ+ people, I will never understand what it feels like to be a woman sitting in a room with multiple male managers doing a performance review.

While I agree best person for the job, these perspectives I cannot possible put myself into are part of that best person. So maybe they cant screw a nut as fast, they can help me understand why we need to do it this way from their perspective, which is a perspective I dont have without them.
