Maybe I'm missing something but I can't imagine how terms of safety could apply to a forum such as this one where everyone is anonymous -- I mean, the only way I would think of it as safe / unsafe is if there was a threat in terms of my real identity getting compromised. But, that's pretty much it.

As for being miffed, hurt etc by other posters' responses, again this may be just me but I can't possibly take an anonymous forum terribly seriously -- sure, sometimes I get a trifle irritated (or overjoyed) if someone disagrees (or agrees) with me but other than a brief burst of adrenaline that makes me (hastily at times!) post in response, I don't see any other issue.

If I did find that I was feeling really out of sorts with stuff being said here -- other than potentially very specific, serious trigger warning stuff -- I would personally want to figure out what's going on with my emotional life that a random, anonymous internet forum has the power to make me feel that way. But, then again, I do understand that I process emotions etc rather differently from others and so, I may not be seeing something (correctly).

And yes, I do agree that as far as anonymous web forums go, this one is remarkably Kumbaya-ish (and I mean that in the best way possible i.e., without any snark!). I also absolutely love it that despite the anonymity and lack of detail about people's lives, somehow people's "voices" come through loud and clear -- to me, it feels like a near-perfect blend of "knowing" and still being at a safe (read anonymous) distance.

ETA: I got on to PC about 8 months after starting therapy -- for me, it's made me much less irritated with my therapist!
