I have been a teacher and have met with, and kept, friends from among the many teachers I have met throughout my career.
"Support for bullying is rampant amongst (sic) teachers." Really? Unless you were a teacher, I am puzzled as to how you could make such a statement. It was not my experience. Women predominate in teaching and very unlikely to be bullies. I remember feeling very nervous of some fathers of the children who I would meet on Parent-Teacher evenings.
