Your reality tunnel or (belief system) is generally defined by genetics, parenting, early schooling, sexual awakening and blind luck. That's why societal evolution tends to happen slowly. There are set restrictions that humans must conform to at each state of growth. You can't pass to the 4th grade until you've conformed to the requirements of the third grade and so on. Humans have simplistic needs and tools to aquire those needs. Crying, whinning behavior tends to bring mommy and love is the reward. Dad's love requires a more complex set of skills. Friends and packs require further sets of skills and conforming to succeed. The sexualy awakening adds another powerful hormonal change and comes with all that baggage. I would wager to say that most men are unconsiously attracted to their first love/sex girlfriend. Maybe even marry women who resemble them. Higher Education continues to conforming forces. To get that important degree that provides money (survival tickets) needed to live you have to agree with their thoughts and memorize their appointed agendas.
Add 30 years of wage slaving, kikds of their own, debt and physical deterioation its no wonder this is the planet of walking wounded people. All of your belief systems (BS) are an expression of the creation of your reality tunnel based off of specific neurological imprints at different time in human growth. These reality tunnels also do an amazing job of rejecting infromation that doesn't fit into your "correct belief" system. Welcome to all politics and religions here.
At the end of the day a Born again Christians would be born again Hindus if the set of their live was slightly altered and vice versa
To be born is to be brainwashed.
and for animal (humans included)and vegetal life forms life is about surviving (outsmarting / outperforming and dominating others) fighting constantly, learning -how to better fuck others in the ass instead of being fucked by them-, reproduce with the best female/male depending of our own strenghts/weaknesses, teach the strategies of survival you learned to an offspring, strangers or write them down in a book , which will make you feel "part of the big thing", "useful" ...and ultimately you die. Going thru life blindly, subconsciously, imitating, following what the preprogrammed behaviors, beliefs that you didnt choose and that are embeded in your brain and body "tell you to do", successfully -you dominate and people envy you, instead of being envious of them and dominated by them- makes you "happy" and admired by others, failing to do so makes you frustrated, depressed...but willing to do "better". Nobody likes losers, everyone like dominating characters. Want to learn from them how to become like them. Wether they re fair, moral, loyal or not doesnt really matter for most. People only see "power".
Most people fail to be successful , to dominate, to reach goals -most have none- and only go from a desilusion to another. Still, they have the automatically generated by the reptilian brain "simple" pleasures of life to motivate them to stay alive and wake up everyday. They can envision themselve taking a dump, beating someone else less powerful, eating, watching a soap that will allow them to flee the reality of their condition and imagine they re someone else , the character they re identifying with... And it makes their day.
