In my mind attraction vs. promotion has more to do with the difference between saying “You drink too much and you need to go to AA to take care of it” and saying “Do you think you have a problem? If so, perhaps AA can help.” I am amazed to hear people state that they had never heard of AA and would have come earlier if they had only known. I have no trouble with public service announcements. AA can’t help if it can’t be found.
Speaking here on SR is just one drunk helping another.
