Their only possible response is the one they have taken, and that is to isolate the children and keep them from being exposed to the truth. This has led to the creation of literally tens of thousands of Avoidance Schools where the kids are sheltered, dozens of accreditation organizations as well as the US Home Schooling phenomena.
I see it more as isolating the children from the 'evils' of the secular world rather than truth; after all, their beliefs are accepted by them as the truth.
I am an avid skier in the winter and once a year help a fundamentalist church youth group with a week-long ski trip. On my annual all-expense paid trip with the group there usually are 20 or so kids, most of them home-schooled.I am probably one of the very few 'secular' adults the kids are exposed to and I think they kind of use me as a lesson for the kids in how to convert the 'unsaved' - they are always trying to convert me.
The children are exceedingly polite and well behaved, and in this regards the parents have done an outstanding job. I sense a naive view about the real world, however, and this is no doubt due to the parents excessive efforts at control. Even on a ski trip there is a list of rules that border on the insane - for instance, whenever boys and girls are together, no matter where or when, they must be accompanied by an adult, even while riding a chairlift.
I have discussed this with the pastor before. He implied the level of control that the parents place on the kids is meant to prevent any exposure to temptation or evil. Evolution is never brought up in these conversations. Rather, issues like pornography, sex, drugs, ect. seem to be the concern. They see evil lurking at every turn, waiting to seduce their kids. It is a neurosis or hysteria.
Most of these families home school their kids and there is no cable TV, and they strictly limit what they watch. I asked him if this might be counter-productive as one day they are going to have to go out and get a job in the real 'secular' world. His reply was, by that time their level of Christian maturity will be at a level where they are able to handle the evils that are thrown at them.
My goal is not meant to dictate to others how to raise their kids, but the level of control I see borders on the insane. Once they are free I suspect some of the kids will probably let loose and party like madmen(or madwomen
).
