A lot depends on who is running the meeting. Some individuals are know it alls and try to change the format when the format, if followed really works well and is tried and true. They often ask my husband to chair meetings because he prefers to run them the way that his mentors did that helped him. Also, not everyone attends willingly either, sometimes they have to because they got in trouble and lost their license. Also, those that are more narcissistic often feel it's beneath them and don't care to open up and share. They are more apt to walk away deciding those in the rooms are a bunch of losers. It is this type that tends to be angry drunks too. These are the die hard deniers that tend to practice shaming.
