Lol, I was listening to a Bill W tape yesterday in which he talked about their initial notion that somehow they were going to work with something called a "pure alcoholic". As he says, at one time the rules they had, if they were all in force, wouldn't let ANYONE into the fellowship and the programme!
I have sympathy that some people are just "problem drinkers" and some are "alcoholics". But I have complete confidence that it is neither within my power, nor is it my responsibility, to sort out which is which. If I had a "compulsion" to start examining which people should be in and which shouldn't, I would hope I would be able to do a step 10 number on myself!
