It certainly is crazy. I appreciate that the author left hints and certain introspection about how it could be a self-irony. However the author seems mostly still believes in it being true. Looking at the "evidences" he put together they're mostly frail and nonsensical, especially the motive part. Rational people would certainly avoid failing prey to such obviously irrational rut. Good for being sane enough at times to remind readers about that, though.
