Logician, thanks for agreeing, and I agree with your reason as well.
The little I know, it seems you are describing some schools in the larger Jewish communities that cater to specific types of Jews. While I may not agree with how they are run, I can understand why, for schools like those, where they DO instill a specific type of hashkafah, it is important for the parents and school to work together and definitely be on the same page. Because if they aren’t, and if they aren’t working together, then chances are the child will receive one type of hashkafah at home and another at school, and that can be dangerous, as you said. What I (and I think Logician) are saying is that if the school is “neutral” in terms of specific hashkafos, and the children are simply going there to be educated, and their own hashkafos come almost entirely from the home, there is no danger in that.
big deal, true, it is possible that children do not have the maturity to use these things responsibly. And if they aren’t mature enough, I agree that it would not be beneficial to inform them of how to use it. At the same time, parents should be extremely aware of the maturity of their children, and understand when they ARE mature enough for these things. Because these things are best absorbed when taught by parents, or at least a figure that the child respects. Because if not, they will probably learn of it from other, less desirable sources, and chances they won’t be mature and responsible enough to know how to use it properly then. There is no set age where such a thing should be taught. Every child is different, and the parents should understand that. I agree that banning means nothing, and usually backfires almost every time. We definitely need to teach appreciation, encourage responsibility, and show trust.
Toi, I actually agree with you that Facebook is almost always unnecessary for children, and there isn’t really a reason they should have it (there may be a special circumstance, but generally, it’s not necessary for them). But for things that would be beneficial to them , I agree with zahavasdad that teaching correct usage is far, far better than banning.
