If you stack your council with people of entirely one viewpoint, there's little point in having a council at all. Create a board entirely of Muslims and it's going to say we should fast during Ramadan. If Google tries to cite that board as an ethical authority to justify a policy of mandatory fasting, they're not going to convince many people.

With a diverse board, the answers to some questions are going to be inconclusive. But that doesn't mean the board shouldn't exist at all. And it certainly doesn't mean we should eliminate all diversity in the board.
