I don't think I can. I gave an example of how people speak colloquially. For instance, one can mention Christianity in a discussion but that term means different things to different people. People will say things like, "Christians believe this..." without it being literally true. Most people speak colloquially and not in a technical sense. The phrase "Ayn Randian paradise" does not imply the sort of paradise envisioned by Ayn Rand. It's a reference to a belief commonly held by people who nominally agree with Ayn Rand's view as they understand it to be.
