I am still needing the quote from guidelines that we can't analyze each other

because, imo, we live life doing that. We make judgments as to what we think someone is trying to express, and we determine what we know that might help them. If that's what you call psychoanalyzing, then so be it!
No problem discussing this at all, imo. I'm sorry that you feel you might be crossing that invisible line you look for
I agree with Septembermorn that we aren't to
diagnose and add that another difference is to make our posts as statements of what WE know and think, not necessarily what the experts say (unless we say that or quote them.)
That's why IMO is such a nifty 3 letters! Take care.
