truth or consequences
I don't see anything wrong with hero-worship — cultures all over the world partake in such activities. But, generally speaking, the guy's got to do something heroic first! This is just common sense.
In America, they like to idolize Hollywood stars — somehow imagining that the heroic deeds done on screen are real. Such dilusional thinking turns idolatry, which is already bad enough, into a kind of false hero-worship.
In aikido, where we are supposed to be expanding our awarness, such pursuits are clearly counter-productive.
