Although I agree completely with the view "Trust no authority or leader. Decide for yourself!", I will strenously and vehemently argue against the sentiment: "Trust no-one over 30!"
For a very good example of people over 30 who have NOT been brainwashed and in fact have done immeasurable and invaluable work creating the foundation for the work you're continuing, check out the numerous interviews at Mavericks of the Mind and Voices from the Edge, just for starters.
Not all of us old fogies are brainwashed establishmentarians - some of us have been fighting this battle for many, many years. =)
It's very good to see such enthusiasm, no matter what age. =)
