Great article on isolation verses insulation when raising children.
Sheltering Children: What it is Really About
From the article:
There’s a big difference between knowing about evil things that can happen and knowing evil by being steeped in it. It is certainly possible to shelter one’s children too much so that they are ignorant of reality and have no idea how to function in society or how to address the wrong ideas of the world. But that’s very rare. The greater danger is in putting children in the midst of evil before they are prepared (developmentally and spiritually) to handle it. That is by far the more common scenario and the one more likely to result in problems.
