Agree with BK's assessment from being there. These are some points I think should be taken into consideration.
On top of being disorganized, many are highly emotional. This adds to it being disjointed.
IMO, I think they are justified in disrupting the meeting for purely selfish and cathartic reasons (you tube aside). I base this on the principle of silencing/not believing allegations of abuse. This can drive people over the edge. I would expect to see more of this as more people exit, and would presume the videos alone could play a part in some waking up.
Add the two witness rule, to witnesses don't lie, and the kid has an active imagination, and abuse is silenced. So, yes this organization is so destructive that it deserves no respect.
