stupidity and fear.
You keep people in ignorance and then scare the shit out of them, they transform into puppets!
It is their attempt to suborn free will so they can control human behaviour. The best way to control human behaviour is to so deeply condition the being that the being's own mind becomes the judge, jury and executioner of "unacceptable" thoughts, words and deeds.
"What went wrong in how we raised you? We did our best and yet you turned out this way."
By THIS way they mean, not a puppet feeling obliged to obey the status quo of said traditions and culture regardless how outdated and obscene some of their normalcy maybe! Le Sigh!
That's because the ideas of free thinkers will always challenge the unexamined beliefs of the conditioned, who feel fear when they encounter an idea that contradicts their conditioned beliefs.
Rather than allow it in - that would mean they had to THINK about it! They denigrate the messenger, and will even kill the messenger if the message feels too scary to that mind.
When we are not addicted to our own beliefs as a result of our conditioning, we can hear competing ideas and not feel fear around that.
We simply choose to accept the idea or reject it without emotional prejudice.
Some are elevated to the status of prophets, saints and demy-gods, and then new religions are formed around their teachings to create a brand new field of separation between the enlightened being and any followers.
In this way the power/dominator system maintains its stranglehold on authority.
Today, anyone can become enlightened because it's part of our evolutionary trajectory.
We no longer seek a messiah from without to inform us how to do it; we have been gifted enough tools and mental capacity to do it for ourselves in modern times.
Economics is about who holds the power to access the planet's natural resources, and to forcibly deprive others of the resources necessary for their well-being and happiness based on "ability to pay."
Education is about who holds the power to determine what is true about reality and to forcibly infuse that understanding into others through the use of rewards and punishments.
Medicine is about who holds the power to determine what is healthy and what is unhealthy, and to then coerce people to behave in ways that have been deemed healthy.
Culture is about who holds the power to determine what is fashionable and what is unfashionable, and to use shame and desire to coerce people to comply with the cultural norms.
The negative feedback we're receiving from reality is informing us that our behaviour is life-negating. That behaviour is a function of our conditioning, so in order to change the behaviour we have no choice but to shed the conditioning out of which it arises.
As we begin to see the chinks in the armour of our own conditioning and shed one belief system successfully, it becomes easier to shed the next one, and the next, and the next...until the mind is free.
We act this way because we've been taught to believe we have dominion over all else, and that we are free to exploit what is not 'as good as us' for our own gratification.
