No it doesn’t. I obviously understood my old posts (and still do—the posts make sense if I imagine ignoring LDSL). So I’m capable of understanding whether I’ve found something that reveals problems in them. It’s possible I’m communicating LDSL poorly, or that you are too ignorant to understand it, or that I’m overestimating how broadly it applies, but those are far more realistic than that I’ve become a pure crank. If you still prefer my old posts to my new posts, then I must know something relevant you don’t know.
