I feel like I have my finger in the dike's leaking hole. It might take writing a book myself and I do not feel up to the task. My career skill is architecture and I can't draw my objections to this and many other authors approaches to left/right differences and things in common.
As an older man I have struggled with left/right conflicts through one divorce, mother, father, plus siblings that are on opposite sides of left/right. My reality is Liberal. Perhaps the "elephant" chooses my course. I doubt it.
If we are each on our elephant we are a society of elephants but a herd of elephants. If so then each elephant is not leading it's rider the whole herd is leading each elephant. Someone is leading the herd with intellect because they are riding one of those elephants. If that is confusing let me get to the point.
Years of trying to find a path of understanding I finally asked "why do people hold conflicting facts in harmony" as their reality? There's a chapter of explanations. Men are often color blind some women too ok? No matter what they are told they cannot see the true of color. Same in left/right realities. Left builds it's community based on ETHICS. Right builds on MORALS. The author bases his book on morality and says he is right/conservative. See the problem? Another chapter.
Next Chapter: Right builds their family on children with RESPECT AND FEAR of Strict Parents (painful spankings, i.e. tough love) w/self defense, morality, discipline. Left builds their family on children with RESPECT AND TRUST of Nurturing Parents w/Openness, Empathy, Reflection.
To keep it short look at "common" career preference. Right/conservatives seek careers with authority: police, judges, stockbrokers, sales and military (Right are called "hawks") Left/Liberals seek careers to help improve others: teachers, scientist, professor, architect (me) and MEDIA (Left are called Doves). Right complains about left careers and Left complains about right careers.
I can go on for many pages this is not the place. Bottom line: If you believe in Evolution, not popular with conservatives, why would you think it ever stopped? Left and Right people look the same and act the same in countless way but they are not the same.
It is not about elephants it is about TWO SPECIES both mistakenly called humans. This is about two distinct and separate species of the same humanoid tree of evolution. One will eventually displace the other. My guess based on individual realities Liberals are the Progressive species and will dominate. That is why monarchies are diminshing and human rights are becoming less dependent on top down power.
We on the left want a better life expressed as a LEVEL PLAYING FIELD where all have equality from birth to death. Where wealth and power are obligations to those who need a helping hand to better themselves and EMPATHY is abundant. The Right has always preferred top down power and rule by the strongest. Right reality is Survival of the Fittest. Left reality is All for One and One for All. It is not about intellectualism or elephants or herds or morality and religion that is another chapter which the Left often appreciates better than the Right starting with Sermon on the Mount which the Right seldom if ever refers to because it teaches the opposite of Right values and morality, LOL But they know they are Christians in a Christian Nation of Morality? LOL
