bags first of all I'm not upset. I started to get cross when the thread turned against the victim, left to have a coffee and am back. Let me get one thing straight when it comes to bullying. You have to listen to the person who is being bullied or alleging bullying. In the same way you have to listen to victims if other abuse. For too long they have been dismissed as 'whingers' or even liars. It's not up to the bully to hold the balance of power and define what bullying is.
I'm pleased you felt able to report something to GNHQ. Not everybody feels they can 'run to teacher' . I feel strongly that we should police the threads ourselves as much as possible, and that includes pointing it out to someone who is in my opinion going too far, being too personal, rude, insensitive, etc.
To return to the OP. it mentioned 'bickering' I think. This thread has explored hat happens when bickering turns into something worse. That's good, open discussion. We need to learn how to deal with this issue, not put it down by saying it doesn't happen, we knows it does or by trying to make the victims feel small and worthless, which is what sometimes happens. No one should be driven off a thread or worse driven from GN. Both have happened.
