Doc, I understand your comment and the "brainwashing" power of the public school system. My responsibility as a parent was to counter-act as much of that propaganda as possible all through their school years, but that takes dedicated involvement in working with one's school-age children and providing points and counterpoints to the "official" dogma. This not only gave them a different point of view, it enhanced their critical thinking skills and prepared them to think about the content of their lessons and to form their own opinions.
As far as "guns" were concerned, they learned early on that a firearm was not a toy, but rather something to respect for its power to destroy, maim or kill. All three of my sons became proficient pistol and rifle shooters at an early age, and I never had any problems with "curiosity" or surreptitious access to any of the firearms in the home.
My basic point is this: We as parents are obligated to provide educational opportunities for our children, either through public, private or home schooling, but we remain primarily responsible for their education. That means we must interact with them to understand what they are being taught and to provide additional or contrary insights into the subject matter. Unfortunately, too many parents just "send their kids to school" and have no idea what they are being taught ... a very dangerous situation. By sending them off to school, we must not give up the primary responsibility for the quality of their education, else we will someday be very unpleasantly surprised at "how they turned out."
