The ego is the sense of being a separate, self-created being. In such a condition, the Creative God is denied, and that denial of authorship generates guilt. The guilt is intolerable so projected out, and my internal state is everyone and everything else's fault, just not mine.
The ego, to survive, must deflect the attention from it as the source of guilt. It becomes genuinely vicious when threatened, and the biggest threat is the notion that each person is responsible for their feelings: that no one _makes_ anyone feel anything.
No wonder challenges to narratives about causal chains extending into the past, to other people, to other groups, to the body, to the brain, at individual and broader levels, are responded to with such viciousness.
No wonder, also, the very widespread resistance to the AA programme and its ideas within the fellowship of AA; in fact, that resistance and the concomitant dwelling on victim narratives are the rule not the exception in many AA groups I have attended.
For a good fifteen years in AA, I resisted this idea:
