Barb of Washington passed along this salt and light argument by homeschooling dad, Voddie Baucham. Several Bible verses, a strong thesis, and no attitude make for a nice piece. Since I think that K-12 education is not a legitimate function of government, as, say, a police force is, I respectfully disagree with Dr. Baucham's concluding remarks.
Moral and philosophical issues aside, would you want your child(ren) in a school where the teachers also had to assume the role of custodian?
