If I had a philosophy that my children were not allowed to attend school under any circumstances, I would have been honest enough to not downplay their natural curiosity, but rather tell them that despite that, they would never be allowed to choose school. Not being snarky, just saying that I personally feel that if our choices for our children's education are paramount, then we should just be upfront about it because it means that the child's views or wishes essentially do not count, and won't count. You can present it anyway you want to, but in the end, the parent controls the decision making, so why worry about what other kids are doing? It won't ever really matter if there aren't choices or conversation. JMO.
OP, I must say I slightly regret letting my youngest child (in particular) watch as much TV as she has. All she watches are shows that promote school as great and I find it grating. She has never expressed interest in going to school, but I do find the constant promotion of school grating. It is such a school dominant culture we live in.
I would not limit exposure to generally positive people, though. I would be careful not to link doing worksheets with school - indeed many worksheets are done at home by HSers! I would also not limit contact with friends who talk about schooling, but I would endevour to give a balanced view as time goes on.
