Al-Anon taught you to accept this drunk's list of excuses? That is terrible! I couldn't think of anything more unhelpful than to teach a family to believe these blame shifting excuses.
What a perfect set up for a drunk to "relapse", having a family that believes the whole drunk excuse book, hook line and sinker.
You apparently believe that AA and Alanon are more of a problem than a help. It seems that your belief is so potent that it has caused you to be antagonistic toward AA and Alanon.
Why is that?
Have you directly assisted in helping an alcoholic (not just some one who drinks) to recover from the illness?
At times you seem to have been open minded, saying things to the effect, "If it works, then fine." However, the most forceful elements of your comments seems to hold that AA and Alanon are destructive. Or at least that the stated principles of these programs relating to the character of the illness are destructive.
