It's a mixture. Intellectuals look back at historical events and re-frame them to fit a larger mostly manufactured narrative structured as propaganda to advance politics. Great humans with actual oratory talent exist and inspire, because they carry a fire that lights your own.
Consider for a moment how far we have come in reverse engineering the human mind through trial and error. We are on cyclical paths of constant upgrade:
When you look at a perfectly formed woman or man, you feel a mixture of lust, regret, shame, desire, hope, fear. Then you hear them talk and the illusion is shattered as you realise they are far from perfect.
When you look at an old, ugly, malformed, disheveled, fat, disgusting woman or man, you feel pity and ridicule. Then you hear them talk and that illusion can also be shattered, as their voice, their command and expression, their poise or grace can transcend their physical infirmities and elevate them in your mind's eye.
The fat woman becomes the loving mother or grandmother who sacrificed her youth and beauty to raise and care for you. The ugly broken man with a bowed back and torn hands becomes the loving father or grandfather who built your life with his sweat and blood.
Now what happens when you have CURRENT YEAR impressionable youngsters looking at their elder orators? They see the fat woman on welfare, single parent, barely present in her child's life, complaining about men or race or the world not being fair. They see an old pervert, leering at them, a man who dodged the draft, never fought in any wars, wasted his youth on drugs and alcohol and then in abject and pathetic materialism surrounded himself with status bought, nothing earned. Spoiled generations who had 15% interest rates, massive GDP growth, cheap housing, stable jobs, who living in the perpetual shadow of MUHNUCLEARWAR voted for larger and larger governments which took more and more of their freedoms away.
This is natural and by design. This is EXACTLY what the young people in the 1910s saw in China, Russia and America. Then they got fucked. First economically, then militarily. A lot of them died, and out of the leftovers they rebuilt, sacrificed, and promised to themselves that their children and their children's children would never suffer.
These cycles repeat through history as a mechanism to create the incentives required to progress the technology to a higher level of prosperity. While I have no direct evidence for it, I am quite convinced a parallel evolved or foreign species is manipulating humans for tens of thousands of years, to rebuild their own lost civilizations, and they are simply running us all through the meat grinder of progress, carrot and stick. This process happens naturally over many hundreds of thousands of years, but is being accelerated artificially, and in this age of information it is easy to piece together this puzzle and see something smells rotten here.
I'd say, strap your dick to your leading leg boys, the jews are taking us to war (again).
