Me too. I certainly know far more people that home school their kids to comfortably raise them either without religion or non-traditional spirituality. That probably has more to do with where I live and my circle of friends though than I'd think is representative of the country and I fully suspect plenty of parents are home schooling to raise their children with strong religious dogma. This seems weird to me though since so many parochial schools exist in the US.
In my experience there is a strong bimodal distribution: one group does it because they don't want their kids exposed to the secular world until they are adults, and the other group is dissatisfied with the quality of the educational facilities available in their area.
