Despite considering itself a secularized political ideology, which is not based on beliefs about deities and/or metaphysical dimension, the "left" has structurally behaved like a kind of religion and I will demonstrate this through a list of indicative signs:
1. It tends to be based on narratives rather than facts
Narratives are preconceived (and typically simplistic) interpretations of phenomena, situations or events, generally closed to criticism or intellectually honest updates. An example of a "left" narrative is that of "white guilt", which states that especially white people of European origin should be collectively held responsible for crimes committed in the past and present, omitting bad actions of other racial groups, including against whites, a narrative that expresses a fallacy of suppressed evidence, in which "half a story" is told.
2. Tends to present a dogmatic style of thought
Because it presents a narrative structure, this structure is also constituted by dogmas, which are statements or thoughts considered as absolute truths within a certain system of beliefs and which, characteristically, do not correspond to facts or objective truths. The dogma of human equality is an example widely adopted by those who identify with the "left", that there are no intrinsic or more pronounced differences between human groups (sex, race...).
3. Tends to be based on beliefs without true or forged evidence
In other words, it tends to be based on faith, on blind belief in certain postulates, generally based on forged or false evidence. The blind belief that there are no human races or that their differences are only superficial, of "culture", is an example of a "leftist" belief without true evidence or with false evidence (fallacious arguments).
4. Tends to base itself on emotion/subjectivity rather than reason/objectivity
Although not "everything" it defends or believes is untrue (it is much more complex than that), it often uses appealing methods, such as emotional blackmail, to convince or defend its points of view. Although it is not always intellectually dishonest to appeal to emotion, the "left" tends to show an unhealthy preference for this route, indicating that it does not have a strong enough rational foundation to prioritize objectivity and impartiality in its approaches.
5. Prefers language that is more abstract or metaphorical than literal
For example, the "left" obsession with certain terms, such as racism, clearly an abstract term, a human fiction that is taken as a fact as solid or real as a physical element of nature, and which, on top of that, has been used to promote the silencing of dialogue or criticism of its definitions and applications. Because, like a typical religion, it abuses metaphorical language, treating it as if it represented something beyond the abstract dimension. This type of intellectual conduct contributes to poor judgment. For example, attributing blame for violence to weapons, and not to those who use them to commit violent acts, is an example of poor judgment because there is an inversion of factors, attributing causality to an inanimate element.
6. It presents a mythological pantheon
With leaders or political figures, artists and other types of "illustrious" people who stood out historically and were raised by the "left" as their untouched myths. The biggest difference is that they are not Greek gods from Olympus or Catholic saints, but flesh and blood humans, and full of contradictions...
In addition to a pantheon of "admirable" people, it also presents a "black list" of "execrable" people (true or not, or more exaggerated) that "leftists" love to hate, their pet "goldsteins" (according to the representation of the "personification of evil" in the classic of universal literature, "1984" by George Orwell, and which faithfully shows all the traits of indoctrination and fanaticism of totalitarian political regimes).
7. It is proselytizing and irrationally intolerant
Very similar to most traditional religions, followers of the "leftist" religion also seek attract new converts, often in an aggressive manner, in addition to contributing to keeping other followers strongly indoctrinated, always aiming to impose their opinions and beliefs through all means they can dominate, legally, culturally... instead of tolerating a broader spectrum of ideological diversity or ideas and thoughts, especially those who are more sensible (regardless of their origin in the political-ideological spectrum), and seeking to honestly criticize their own beliefs.
