I'm not sure how strict the borg is these days about "drunkenness" but in the late 1980's I was in a cong where not one but two sweet, harmless sisters in their 70s were DFed for just that. I know the "inside story" because one of them was my Aunt, the other was a distant cousin, and the PO was my Uncle.
Both sisters were born in, lifelong active and faithful in every way. Both suffered horrible trauma from physical and emotional tragedies and found some solace from alcohol late in life. Both were seen ONCE at a restaurant somewhat tipsy. They were told on and counseled by the elders. Surprise surprise they relapsed.
Mind you, AA was highly discouraged and no help was offered or given to these poor souls. Although they both attended the meetings, sat in the back and suffered for years they were never reinstated. (reoffending) They died with the indignity of being DFed.
AMIII and the Borg he represents has done nothing to help people with addiction problems. Their MO is to ignore or worse yet, punish people in need of help.
So if AMIII actually does have a drinking problem I simply hope he is dealt with the same as my dear Aunt.
