Jan, I read the whole thread before posting, but overlooked that Bern is the author of post 1, sorry!
Bullying often starts with small acts of disrespect that, unchecked, continue and get worse. There is also the group factor, where one encourages the other to join in.
Harasment of vulnerable people should be dealt with by various sectors of society, including parsons and priests, teachers, parents and local organisations that are open to society.
It means teaching children what is right and what is wrong.
However, for the record, I would not walk by and pretend not to see, if I saw someone being bullied.
But my every-day experience tells me that the vast majority of people are not bullies, children included, and that is what I wanted to point out too.
