I think that 'auto-critique' fundamentally works to preempt (expected and unexpected) critiques by others. One criticizes oneself in the secret hope that one won't be (badly) surprised by becoming an object of others' criticisms. In other words, 'auto-critique' protects our fragile ego from becoming wounded. In this sense, 'auto-critique' is a defense mechanism one develops in order to manage the fear and shame of having one's own (inescapably) partial vision exposed in front of others. It is what we do so as not to get 'caught with our pants down,' so to speak. It is a sign of the lack of solidarity (or of trust in our friendship/comradeship with others). That is why I heavily discount the value of navel-gazing about 'privilege.' It is not just an impossible task; it is also a smarmy gesture.

Perhaps the above is one of those ironic one-liners that do not require any reply, but let me pretend ignorance and answer that 'auto-critique' allows us to feel we are so wonderfully above being defensive of our little ego, thus giving us a pleasant sensation of anti-narcissistic narcissism.
