Despite Russell plainly stating "... bear in mind that the end of 1914 is not the date for the beginning, but for the end of the time of trouble", the Watchtower in fact did end up teaching that 1914 is the beginning of the time of trouble.
You have to wonder about the organization's desperate need to keep trying to prove it never said the end would occur in 1914.
Besides, there's a monumental difference between (1) unabashed pure speculation about the end and (2) demanding all members submit to the pure speculation under threat of expulsion. The Watchtower Society is guilty of both 1 and 2.
Unfounded speculation I can tolerate but expelling members who question the unfounded speculation? The latter is what stamps the Watchtower Society as monstrously hypocritical and damned by its own self-important religious pride.
