The assertion goes like this: 'AA tells you to take responsibility for everything, but that's wrong. Bad things happened to me as a child, and I'm not responsible for that. I can't just forgive people. My sponsor told me I need to get angry over what happened and sit with that, and somehow I'll get over it.' (Pretty much verbatim.)
This is sometimes accompanied by objection to the assertion that we are selfish and self-centred. Perhaps, also, this is viewed as encouraging shame.
Let's look at where this might come from:
'Selfishness—self-centeredness! That, we think, is the root of our troubles. Driven by a hundred forms of fear, self-delusion, self-seeking, and self-pity, we step on the toes of our fellows and they retaliate. Sometimes they hurt us, seemingly without provocation, but we invariably find that at some time in the past we have made decisions based on self which later placed us in a position to be hurt.
'And there often seems no way of entirely getting rid of self without His aid. Many of us had moral and philosophical convictions galore, but we could not live up to them even though we would have liked to. Neither could we reduce our self-centeredness much by wishing or trying on our own power. We had to have God’s help.'
