I do respect my 'HE is the only way' friends, even though I don't share their view. Tbh, I know plenty who hold to that view who aren't actually Christians anyway It's an opinion, like any other, no more or less valid than those who hold to the opinion that school is the only way.
And there are many Christians who hold to that one purely from a 'child-as-evangelist' viewpoint, which I personally find just as questionable as the hyper-sheltering view.
As far as I'm concerned, I'm quite unashamedly giving my children a faith foundation, because that's the culture of this family. I don't subscribe to the idea of neutral, being a good post-modernist so I'm not going to attempt to present a neutral worldview to them. Our ethos is pretty much the 'classical' approach, which in a very rough shorthand, means teaching them to think, analyze, use logic etc.
At the moment, my children are all at an age when everything is concrete and black and white anyway, so I'm not imposing anything on them iyswim. My eldest is just beginning to grapple with interesting questions, and coming to terms with the fact that not everyone sees the world in the way she does.
I certainly agree that isolationist motivations can lead to seriously distorted viewpoints, but I think, as long as you help them engage-brain, it's very avoidable. My family isn't Christian, so I couldn't cut them off from non-Christian influences if I tried (and actually, with my family, I've ruddy well thought about it before now, but I digress...)
Actually, i'll stop there, i can hear the computer hamster dying on me...
