Allow me to point out that some of these incidents wherein people "went apeshit" with "delusions" had a basis in fact. In Europe and possibly in the Witch trials in early America, Huntington's disease was undiagnosed: http://curehd.blogspot.com/2008/08/roots-of-our-stigma.html As for other "delusions", I would point out that even Carl Sagan felt that childhood evidence of reincarnation needed to be investigated, rather than written off. There is a huge body of work on this via Stevenson ( Old Souls). If eyewitness testimony is given decisive weight in some circumstances, then it should be a simple matter to find cases that repeat those conditions and end this nonsense about "extraordinary claims needing extraordinary proof". Such "logic" suggests that there is no such thing as "proof" in the first place and beyond that, keeps moving the goalposts whenever infidels find it convenient to do so.
