Politicians are brainwashing your children. TV is brainwashing your children. Biased textbooks are brainwashing your children. Environmentalists are brainwashing your children. And, yeah, some teachers are doing it too. It's our job as parents to make sure we know exactly what our kids are being taught by everyone and everything in their lives. If we do our job right when our kids are young, it should be easy to keep up with the occasional inept efforts to indoctrinate our kids into irrational thought patterns.
