Well, why don't you listen to white supremacists? There are a number of them in America, and they certainly feel aggrieved. Shouldn't they have a seat at the table, to support diversity of viewpoint? What if they've got some points?

This is the fundamental meta-question of appointing an ethics committee: you have to have some idea, already, of what is ethical. That idea could be—but probably isn't—to follow the world around you in proportion to their beliefs. That idea almost certainly is to follow your own existing sense of right and wrong. You want to find people who seem better at you than reasoning but the same as you in ultimate values. You want people who are going in the same direction you are, just better at getting there.
