Well, as I pointed out in my other comments, unless I answered your challenges with essays of enormous length, my answer would consist of multiple assertions without supporting evidence that sound outlandish on the face of it. Remember that we are talking about delusions that are presently shared by the experts and/or respectable high-status people.

Note that you should accept my point even if we completely disagree on what these high-status delusions are, as long as we agree that there are some, whatever they might be. Try to focus on the main point in the abstract: if delusion X is low-status and rejected by experts and high-status people (even if it might be fairly widespread among the common folk), while delusion Y is instead accepted by them, so much that by asserting non-Y you risk coming off as a crackpot, should we be more worried about X or Y, in terms of both the idealistic pursuit of truth and the practical problems that follow?
