Free speech are great since start in 1994 or 1996. - - - Updated - - - The Bill Clinton government wanted these.....
Former Atheist and near death experiencer Howard Storm was shown visions of America around the year 2185 and it sure did seem that government was working very differently than it does at this time. http://www.near-death.com/experiences/notable/howard-storm.html#a04 Howard Storm Ph. D. admits that there could have been lots of technology there... but perhaps by the year 2185... it was so compact and fitted into the environment so well that he could not notice it.
Well it appears that gandrews, by default does not oppose Americans defining that free speech have an ultimate purpose. With free speech serving it's needed purpose the prescience of Storms vision may easily become a reality. The structure of purpose valuation of free speech ends up in the realm of enlightenment, inspiration and education. Which is what you are defining in relation to teaching children, within the actions that define our evolution.
