One of my frequent criticisms of religious believers has been the dishonest way in which they profess to humble themselves before a transcendant ideal which, upon closer examination, turns out to be nothing but a projection of their own narcissism. The "true" message of Christianity, for example, amazingly, incredibly, shockingly turns out to be identical with the temperament and culturally shaped beliefs of the speaker. They proclaim themselves lowly servants of a greater whole upon which they nonetheless assert unrestrained creative control. They feign innocence while digging up buried treasure which they themselves planted under cover of psychological darkness.
It's not much different when it comes to identity politics. White social justice warriors pride themselves on their magnanimity upon ceding "control of the dialogue" to representatives of marginalized groups. If you think you detect a conveniently self-fulfilling prophetic aspect to how those "true" representatives of black interests, feminist interests, etc. are chosen, never fear. There's a white guy over there with polls, graphs, statistics and unimpeachable rationality who has already figured it all out for you.
