With all due respect Xanthippe you could then have asked then why did the J.W`s/ G.B.
keep promoting dates going back to the late 1800`s well into the end of the 20th Century whereby the New World should have been ushered in.
All those dates have been well documented here and elsewhere including the WTB&TS own publications .
1874 ,1879,1914,1918,1919,1925,1975 ,2000 , if that does not prove they are false profits I don`t know what else could convince the gullible.
