Hi Beth,
Respectfully, I would hate for the whole board to get all cramped up over what it's okay to talk about.
IMO, almost any subject is okay. Rambling around topics in a relaxed way is one delightful feature of the safety I feel here.
What matters to me is the tone of the board, which is almost always friendliness, benevolent intention, true listening and supportiveness, and mutual respect. There are exceptions, but they usually smooth away after a little effort.
Disrespect and contemptuous tone and dogmatic insistence on one's own view are what sink communication, imho, not the subject matter.
I do want to talk about N issues but I think there are many branches and side-currents to N issues that may seem unrelated...and I'd hate to lose the spontaneous trust I feel to just sit down and type about my life, or respond to someone else's.
Loving intent and self-control of anger ... when those are in place, I think whoever's posting is okay. And it's important to remember, I think, that the only posts we can control are our own. (Richard also takes responsibility as moderator for protecting the board, so there is a safety valve in him.)
Other than that, I think the best response to hostility or serious aggression is no response. I think the action of not responding is more effective than more words about it. That's just my take on it...best I can do.
Hops
