Let's label this support function for what it really is - collective guilt. Spreading the blame.
Most people are unable to accept the horrors they have caused when bumbling around as chronic drinkers. Always causing problems, confused, in trouble, juveniles basically, whining all the time.
So it is crucial to the psyche for the group to bear the responsibility. "I didn't get enough support."
Or: "You didn't make a plan for enough support."
It is of course a smokescreen to shield each member of the group from the personal responsibility of their horrid actions while drunk.
As if strangers on a website saying, "You can do this, I am with you," means anything. Just look at the horrors on the other sections for proof how well this works.
AVRT however exposes the truth. The truth of the nastiness and the selfishness and the darkness. No one else can expiate that. Only the drinker by permanent abstinence.
