EllanVanin, the teachers you are referring to are sexual predators. NOT proper teachers. This has ALWAYS gone on. I remember 2 teachers who were like this when I was at school. The difference is, then it was all hidden and swept under the carpet.
As with any child abuser, they are very careful to hide and cover their tracks, so no one can tell.
Please do not tar proper teachers with the brush of perverts.
While I totally agree that these people are sexual predators, surely that also goes for sexual predators in any other walk of life be that clergy, medical, the police, social workers etc etc. Are they all to be disassociated from their professions, so not proper clergy, proper medical practitioner, proper police, proper social worker? Sexual predators will always try to gain easy access to their preferred prey, and if they are able enough to qualify as a teacher for example that will ensure a steady stream of potential victims. Of course the vast majority of teachers, like the vast majority of people, are not sexual predators.
To return to the original post, respectful engagement with all others must start from toddlerhood in the home, but does need to be reinforced by schools as the child progresses. I'm not necessarily advocating specialist lessons throughout the education years, but a zero tolerance for disrespectful behaviour in all areas would be a good start. School enforcement of acceptable behaviour is even more important for those children who grow up in homes where this isn't the norm. Society as a whole needs to be more willing to challenge unacceptable behaviour in public instead of wilfully ignoring it.
