youre conflating context with intent a bit here knowing a bit about the context and source can be important for example forgiving mark twain for using the word nigger because of the time and context for the writing similar with the edwardchristian example however true intent is far less important the author intended to communicate something and you read something maybe an editor in between sharpened a particular phrase or word that changed the intent regardless communication is a twoway street it doesnt matter what the author intended to communicate it matters what was communicated which is different for each reader
