People just except it because it come from an authority figure in thier lives. Take the example of the overlapping generation teaching. I excepted it for years even talked about it and tried to make sense of it too. When it didn't seem to make sense oh well and just moved on. It was learning about the blood doctrine and the mediator teaching that finally woke me up. 607 and all the other false dates were added in and probably some other crap before I woke to how stupid the overlapping generation teaching was.
This will go over most people heads but as people wake up it will become just another nail in the coffin of thier belief in the cult.
