EXACTLY RIGHT! To those whose only evident core principle is "freedom from government," the notion of a society (beyond the immediate homefront) is incomprehensible. But their children too have to grow up in such a society. If it's a society steeped in TV porn/violence, their kids will be affected--negatively--by that same culture rot.
I know that from sad experience. We haven't had a working TV in my house since my oldest boy was a year old. My 7-year-old daughter today never watches TV. But my grown sons went to school with kids who were raised by the TV set, and my daughter--in a private religious school--is meeting up with similar folk, and she is picking up some of their values.
I suppose the libertarian fanatics would say, "Well, then, home-school them." That didn't seem to work very well for the parents of David Ludwig and Kara Borden, did it?
