Tovia,
Sorry to say, but it happens. On all boards, in all groups. Goodness knows that it shouldn't, that we should be kinder or more sensitive to other peoples' emotions and emotional health but sometimes we slip-up or overstep.
I know that at times I have shown insensitivity without realizing it and I have apologized. It is just that some of us have had 'an experience' with something and we think that it can help someone else. Sometimes, we are, sadly, wrong and it has the opposite effect.
There have been 1 or 2 trolls over the years. But our precious moderators have thankfully, put pay to them and removed them from the site.
On occasion, you can say something to someone and they will take it wonderfully and yet you say the same thing to someone else and they consider it insulting or worse.
I have learned to reread everything that I write, 3xs, before posting it, asking myself if my words are helpful or hurtful and how they could be misinterpreted.
It is sad, but maybe I needed to learn a lesson too.
So please, do not judge us too harshly. We try hard. We are all, mostly, here to help.
Sharon
