A famous and very smart man once said:
"The definition of Insanity is doing the same thing over and over again and expecting different results" (Albert Einstein)
By that definition then, is the society or are witnesses in general insane? After all, they have repeatedly proclaimed dates, or "time periods" for the end to come - that have always proven to be wrong.
Then, they have denied ever having done so.... yet repeat the very cycle for the next generation (sorry, I mean the same overlapping generation)
