Some of the specimens in question establish this, by providing evidence of functional illiteracy when peddling their nonsense.
I suspect a good few of the specimens that turn up here, fall into a very specific demographic. Namely, they’re homeschooled teenage boys from pathologically fundamentalist households, pretending that they’re going to “stick it to the stoopid atheists™” in order to impress some similarly naive teenage girl from their “Bible Study” group, with the ultimate aim of getting into her knickers.
This plan on the part of said demographic, of course, ends up being reduced to a smoking crater in the ground, when it runs into the fatal terrain known as “people who possess actual knowledge of facts and relevant concepts”. At which point his plan to show off his prowess to his equally wet behind the ears lust interest, is rapidly aborted.
This demographic makes itself obvious, when the posts emanating therefrom include such details as:
[1] Basic errors of spelling and grammar;
[2] Woefully incompetent attempts to use emojis and Internet slang, that much more clued up teenagers would point and laugh at;
[3] Obvious failures of even elementary understanding of [3a] the rules of proper discourse, and [3b] the concepts being covered in their failed attempts at discourse;
[4] Appeals to infantile levels of circular reasoning that even other mythology fanboys would regard as embarrassing, such as openly naive declarations to the effect that their goat herder mythology is right just because it says so.
Many of these individuals never developed a proper ability to read, never acquired knowledge of basic facts that the rest of us absorbed with ease at five years of age, or expressed even a fraction of the curiosity that the rest of us exhibited as children. Any that did exhibit normal human behaviours as children, almost certainly had this beaten out of them by the time they no longer needed to wear nappies.
One sad aspect of the pathology being that some never grow out of this state, and remain epistemological infants throughout their lives - sometimes adding ethical infancy to the mix in addition.
