A good article, Witz. And looking at the legislation described, I believe to a large extent it would also cross international boundaries, because it is so closely connected with human rights.
The recommendations - do not retaliate but instead, report to the police (if threatening messages) or confront at adult level (if less severe) and to recognise that it is possible the apparent sender has had their identity hijacked. And legal action is often more possible than we realise, for far less cost than we often expect.
In general, bullies are cowards. When we do not confront them, they feel strong. When we do confront them with all our right and might, they generally collapse like pricked balloons. And yes, bullies are often victims too, and this is their response to the world which allowed them to be bullied. They need to learn that there are more appropriate ways to respond.
As for the "kids will be kids" - that is a parent in total denial, refusing to acknowledge any personal responsibility. It's like people saying, "Am I my brother's keeper?" and thinking it's a GOOD point of view because it's quoting the Bible - it's what Cain says when he's asked where his brother Abel has got to; Cain knows his brother is dead, because Cain murdered him, but ducks out of the responsibility and tries to hide his guilt with that line.
(hmm, maybe if we search historical records from Biblical times we can find the line "kids will be kids"... Herod the Great's father, perhaps?).
