Perhaps our perceptions of and experiences with home schooling differ. In this area, home schooled kids are not at all ‘raised in a bubble.’ Au contraire.
There are networks of home schooling famiies who get together for field trips and share work among themselves, benefitting from each other’s expertise. I.e., if one home-schooling dad is an engineer with NASA, he will take over lesson plans for several home-schooled families and oversee the kids’ education in the math/science areas where he has expertise. That works out better than a state certified teacher whose own math/science education may have ended at the 10th or 12th grade level. And, it is usually far more practical than normal science fair projects.
Presenting one’s conservative case to a teacher, principal or superintendent does little more than get your kid or kids out of otherwise required programs in the school. It also confers on him/her/them an unspoken ‘reputation’ among the powers-that-be who dictate about 1/3 of his/her/their lives. That reputation is telegraphed to other students throughout their school years, rendering their expression of conservatiave viewpoints virtually worthless. It is a perverse form of bullying, done by adults in authority. It is far more pervasive than most people either see or are willing to acknowledge.
