This is exactly the sort of refusal to comprehend so that you can get in an "um, ackshually" that the op is talking about. He's quoting a line from a book as a metaphor for a concept the book illustrates well.
You see someone who you think has missed a larger point, and all you can muster as a reply is a vague jab and unexplained reference? Do you not see the irony? Your whole comment is an “um, ackshually”, the very thing you are decrying.
I didn’t enjoy Dune, by the way. No shade on those who did, of course, but I couldn’t bring myself to finish it.
If you think there’s something there, explain your point. Make an argument. Maybe I have misunderstood something and will correct my thinking, or maybe you have misunderstood and will correct yours. But as it is, I don’t see your comment as providing any value to the discussion. It’s the equivalent of a hit and run, meant to insult the other person while remaining uncommitted enough to shield yourself from criticism.
