Last night had no process and no facilitation...the person who stepped up to facilitate decided to invent a process on the spot, rather than following (or even attempting to follow) the one everyone is familiar with and can be expected to follow reasonably calmly. I left the moment I saw the meeting was being run according to the whims of one person, and that those whims were not conducive to productive discussion or decision-making.
So, there was no opportunity for facilitation and process to break down last night, as there was effectively no facilitation or process.
In short, last night was an example of why we keep holding these teach-ins. There is an expectation in our group that the handful of experienced facilitators are going to drop everything and be available for every GA and every IA, and that simply isn't a realistic expectation. We all have jobs, other projects we want to work on, etc.
We attempted to reduce the number of meetings to four per week in recognition of this lack of volunteers in facilitation nearly two months ago, and two days after it went into effect a proposal was brought up and passed to go back to seven meetings per week (with the alternate days being "Informational Assemblies", but they still require facilitation, just not a full team; last night was effectively an informational assembly, and we saw what happens when an IA is un-facilitated). Hopefully some of the people who were there last night will attend our teach-in tonight and feel empowered to step up in the future, so meetings like last night do not happen again.
Part of stepping back is allowing bad things to happen, so that there can be recognition of a hole needing to be filled. Many of us are trying to step back from facilitation, because of frequent complaints that we're facilitating too often (and because of other projects, and many other reasons)...so, I guess last night turned out to be an example of what happens when no one steps up to fill that gap. Hopefully the hole will be recognized and new people will step up, making Occupy a stronger and more diverse organization.
OK, I ranted a little bit. Sorry about that. And, I'm sorry you witnessed a crappy meeting. I didn't think it would devolve into an ugly meeting. I though it would just peter out into nothing after a few minutes. It dropped from about 25 to a dozen people in the ten minutes I was there, and I figured it'd just keep going until no one was left. I guess I should have realized that another option would be for the dozen people remaining to get really frustrated and angry because the meeting was unproductive and divisive and provided no meaningful container for the conflict.
