Each of the three factions has a blindspot that it taboos and finds impossible to understand. Each faction is held in the thrall. I'll describe a Left wing version where their hero lives in Right wing world and a Liberal version.
So - our Society in caricature.
Left
Suppose you were studying economics or sociology and everybody had a odd paradox they couldn't solve. There were these different groups of people. Some lead long healthy lives and have most quality of life indicators in their favour. The other group has dire outcomes - nasty brutish and short. Nobody can figure it out. The same pattern plays out in different countries and in different centuries. Everybody would like for the people suffering not to suffer but we're perplexed and the newspapers report on a regular basis the status of these people, great people and intellectuals write books about it, classes are held in universities all over the country in the search for the solution.
Then one day some autistic figures it out. It's because some are poor and others are rich. It can be confirmed by checking bank balances. Surprisingly this person does not receive a round of applause and confetti in the streets - he is promptly fired from his job, his friends avert their eyes. Soon he is homeless and is found proclaiming his Truth under a bridge - to find him just turn Left on James Damore St.
Liberal
The Liberals believe in Robots, AGI and similar ideas for artificial humans - have so for centuries. Their fable is the Android - the dream of the artificial human that coincidentally replaces all forms of blue collar labour. The root of the word Robot literally means slave. Their nemesis is the Computer - the information processing machine that works best at replacing their own human generated information processing. Of course they try to use this machine to replace blue collar labour instead. They invest incredible energies here but ignore that each of their schemes for technological and economic improvement is based on some type of forced transfer or even slavery. While technologies not based on theft or slavery exist - these are ignored. They are mostly preoccupied with schemes to move groups of people around the surface of the planet to disrupt their foreign and domestic competitors in the name of social improvement - which it is for them.
I can pass the idealogical Turing test - can't say the same of the people who inhabit Reddit, Metafilter and HN - and I think most of the Right's intellectual firepower remains subtext in our society unless you read old books to find plot holes or the exchange between other civilizations and ours opens up in a way that cannot be censored by the information organs of the West.
