Hero worship is a necessary prerequisite for the establishment and maintenance of authoritarian systems.
Trashing other people's heroes while promoting your own is a classic form of propaganda used by those intent on replacing one authoritarian system with another, or -- more commonly -- by those who seek to acquire the levers of power within an established authoritarian system.
Authoritarian systems cannot be sustained absent heroes and heroic figures from the past.
Thus I tend to be skeptical of anyone promoting heroes and hero worship.
They are in the business of establishing or sustaining authoritarian systems.
