So far I've just read the screencaps that @Relinquish posted of his writing, and it's really bad. I don't mean the content; I mean it's terrible on a basic mechanical level. The sentence construction, spelling, word choice, and punctuation are god-awful. His writing is so poor, it's unbelievable that he thought the reason he couldn't get published was because of the edgy nature of his content. Far from offering suggestions and making minor style improvements, an editor would need to completely re-write everything from the top. It's worthless garbage even if you ignore every retarded idea he expresses and pretend it's something entertaining.
Even if you take out the gore, misanthropy, and masturbatory fantasies, you still have all of the run-on sentences, sentence fragments, punctuation errors, misspellings, redundant word choice ("the abused horse for society to abuse"), and unintentional tonal inconsistencies. The diction sounds like he's writing a forum post but decided to throw in random words like "syllogism" to make it sound more intellectual. His vocabulary, despite the number of books he's read and written, is limited to the point where he finds it necessary to invent words like "unobvious" and "in-understandable." He uses the adjective "viscous" as a noun. His brain just doesn't seem able to retain words and recall them when needed. I'm not sure if this is because of drugs or because he's just that mediocre.
Then again, I guess only real Highly Intelligent Mutants would understand the deep stylistic choice of writing like absolute hot diarrhea on purpose.
