We also have 'open discussion' meetings.
There's also closed meetings. I attend both.
And, I admit that some of the 'open nature' sharing has been 'getting to' me lately, as well. I think any non-alcoholic should share at their al-anon meetings. Period.
Unless of course, they've been INVITED to be a speaker, they should maybe find another place for their preachments.
We occasionally have to interrupt someone who is clearly only 'sharing' because they are preaching, or have gone on too long ... it's understood that it's preferred to do so staying within the sharing baoundaries and suggestions mentioned in the preamble of the meetings. Usually it's the chair who does that job.
I'll be keeping up with this thread with interest.
