These days the rebellion starts from kindergarten apparently. There needs to be balance between understanding and respecting tradition, and questioning it. On one end you have Iran/Taliban, on the other you have modern USA. Galileo was right, and his persecutors were right too.

Yes, but this rebellion is against the PARENTS. Teenage kids typically seek for the new meaning and purpose in their lives, that's why so many college students join charities, or civil rights groups, or cults... And they do not join those groups as leaders, they start at the bottom.
