People just can't handle the truth:

Strong resentment and anger were sometimes directed at the group (then called Bible Students) in the 1910s and 1920s. At the time, this was largely due to the Watch Tower Society's outspoken manner; members carrying placards outside many churches and in the streets proclaiming the imminent destruction of church members, along with both church and government institutions if they did not flee from "false religion" was not an uncommon sight. Typical examples of the Watchtower's attitude are found in the Watch Tower Society's book publication The Finished Mystery (SS-7), 1917 edition: "Also, in the year 1918, when God destroys the churches wholesale and the church members by millions, it shall be that any that escape shall come to the works of Pastor Russell to learn the meaning of the downfall of 'Christianity.'" (Page 485) "The people who are the strength of Christendom shall be cut off in the brief but terribly eventful period beginning in 1918 A.D. A third part are 'burned with fire in the midst of the city.' Fire symbolizes destruction. . . .After 1918 the people supporting churchianity will cease to be its supporters, be destroyed as adherents, by the spiritual pestilence of errors abroad, and by the famine of the Word of God among them." (Pages 398, 399)
