An anecdote: In South Africa - the Anglican Bishops met with their first black Bishop to discuss what position they would take on the new marriage laws being imposed by the Nationalist government. They were all agreed that apartheid was morally wrong and would stand shoulder to shoulder with people of all and mixed races etc etc. They then broke up for lunch and went to the restaurant next door - all except 2 of them (the black bishop who was not allowed into a whites only restaurant, and one other who accompanied him). They went without lunch. None of the others were aware of their privilege or behaviour ... until afterwards. It was this bishop who told the story - without rancour, with good humour and with forgiveness - what a witness to Christ's grace. 
I repeat this story, not to point fingers at the Anglicans but to illustrate how easy it is to be 'righteous' in our decisions and yet unaware of our own collusion in racism (or any other privileged '-ism'.
