Ok. I'm lost here. What if it's a multi-colored board but all are straight?

If I've understood correctly, the requirement is:
NOT (ethnicity=caucasian AND gender=male AND orientation=hetrosexual)
EDIT: Ignore my above, it suggests that no white straight males are acceptable, which is incorrect. See comment below (https://news.ycombinator.com/item?id=22137842)
NOT (ALL(d.ethnicity=caucasian AND d.gender=male AND d.orientation=hetrosexual for d in directors))
It's not like Goldman won't do business with any company with straight white men on their board.
