We don't analyze a content of a mistake, but it's characteristic. Just google the phrase "content of a mistake," before you ask me for evidence.You say mistakes have no content, yet you continue to analyze the content of a small grammatical mistake in a hasty post as if it did.
Let me remind you once again that it was you who pointed toward grammatical inconsistencies in deaman's sentence. The grammar was irrelevant; the sentence features a special/ordinary relationship that matters and which I focused on, because of the unusual cleverness in the composition. You just managed to misplace the point by invoking bad grammar, which prompted the mods to delete the part to prevent further ad hominem cases.
