1. I am amazed at this topic still being up. I am also very happy with the civility displayed here.
2. As a libertarian who is not a Libertarian, I would say that the defining characteristic of a libertarian is someone who holds to the Non-Aggression Principle. Of course, there are libertarian people who don't agree with the NAP, but they are the exception.
3. I don't think Dr. Paul was trying to paint the entire community of homeschooling families with an ideological paintbrush. Imagine instead he had said that baby boomers will contribute greatly to the computer revolution. Obviously he isn't saying that ALL, or even most, baby boomers will be technology innovators. But the people who are, such as Bill Gates, Steve Jobs, Larry Ellison, etc... tend to be from the same era. That's what he is saying regarding the liberty movement and homeschooling.
