Personally, I don't feel they should. If the sexting takes place at school or is somehow incorporated with events at school then the family needs to be made aware of the situation. Sexting is not illegal, at least not when the students are above the legal age to engage in sexual acts.
There is no law against it at the moment. But just like any other sexual act at a young age, it is unhealthy and should be reported to the parents who can deal with it accordingly. It should be in the school's duty to reprimand students, but just as they would reprimand them for similar acts in school.As far as I'm concerned, the school should be concerned with the use of the cell phone in class while the parents should be concerned with what the texts contained.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
