How youth conquered the world
According to Introduction to Youth, a concise and accessible summary of the doctrines and history of youth by renowned youth expert Karen Armstrong, the amazingly rapid youth conquest of much of the world in the 7th and 8th centuries had nothing to do with the youthful energies of the conquerors, but was driven solely by commercial and political factors completely extraneous to their chronological age. It is, therefore, the author says, a terrible slur on youth to suggest that their remarkable expansion had any connection with their tender years.
As for the so-called youth terrorism problem which right-wing American Christians and greedy corporate interests have been making so much of recently, Armstrong points out that it is only a reaction by a tiny minority of the more hot-headed youths to the lack of respect they have been receiving from the aging populations of the West. If the older part of humanity had welcomed the youth of the world with open arms, instead of excluding and marginalizing them, such events as the 9/11 attack on America, which has been vastly overplayed by the way, could have been easily avoided.
