"Mary's cartoons satirize the teachings and activities of Pastor Russell, an individual (designated therein as a "false prophet")."
A false prophet is not necessarily someone who communicates a scriptural inaccuracy or makes a prediction about a future event that fails based on an honest effort to interpret God's Word. While under the direction of God's Spirit, none of Jehovah's Witnesses, the Governing Body included receive any divine revelations that explain Bible matters. They clearly state this:
re chap. 2 p. 9 The Grand Theme of the Bible
Interpreting the Scriptures: The mysteries locked up in the book of Revelation have for long baffled sincere students of the Bible. In God’s due time, those secrets had to be unlocked, but how, when, and to whom? Only God’s spirit could make known the meaning as the appointed time drew near. (Revelation 1:3) Those sacred secrets would be revealed to God’s zealous slaves on earth so that they would be strengthened to make known his judgments. (Matthew 13:10, 11) It is not claimed that the explanations in this publication are infallible. Like Joseph of old, we say: “Do not interpretations belong to God?” (Genesis 40:8) At the same time, however, we firmly believe that the explanations set forth herein harmonize with the Bible in its entirety, showing how remarkably divine prophecy has been fulfilled in the world events of our catastrophic times.
A false prophet is revealed by his actions as an insincere truth seeker:

The Tree and Its Fruit
“Beware of false prophets who come disguised as harmless sheep but are really vicious wolves. You can identify them by their fruit, that is, by the way they act. Can you pick grapes from thornbushes, or figs from thistles? A good tree produces good fruit, and a bad tree produces bad fruit. A good tree can’t produce bad fruit, and a bad tree can’t produce good fruit. So every tree that does not produce good fruit is chopped down and thrown into the fire. Yes, just as you can identify a tree by its fruit, so you can identify people by their actions.
That is why people like Mary use empty headed and false accusations about Charles Russell to further a warped agenda.

Foes of C. T. Russell used not only his domestic affairs but other "weapons" against him. For instance, his enemies have charged that he sold a great quantity of ordinary wheat seed under the name of "Miracle Wheat" at one dollar per pound, or sixty dollars per bushel. They have held that from this Russell realized an enormous personal profit. However, these charges are absolutely false. What are the facts?
In 1904 Mr. K. B. Stoner noticed an unusual plant growing in his garden in Fincastle, Virginia. It turned out to be wheat of an uncommon kind. The plant had 142 stalks and each bore a head of fully matured wheat. In 1906 he named it "Miracle Wheat." Eventually others obtained and grew it, enjoying extraordinary yields. In fact, Miracle Wheat won prizes at several fairs. C. T. Russell was very interested in anything related to the Biblical predictions that "the desert shall rejoice, and blossom as the rose" and "the earth shall yield her increase." (Isa. 35:1; Ezek. 34:27, AV) On November 23, 1907, H. A. Miller, Assistant Agriculturalist of the United States Government, filed in the Department of Agriculture a report commending this wheat grown by Mr. Stoner. Throughout the country the public press took note of the report. C. T. Russell’s attention was drawn to it, and so in Zion’s Watch Tower of March 15, 1908, on page 86, he published some press comments and extracts from the government report. Then, in conclusion, he commented: "If this account be but one-half true it testifies afresh to God’s ability to provide things needful for the ‘times of restitution of all things which God hath spoken by the mouth of all the holy prophets since the world began.’—Acts 3:19-21."
Mr. Stoner was not a Bible Student or an associate of C. T. Russell, and neither were various other persons who experimented with Miracle Wheat. In 1911, however, Watch Tower readers J. A. Bohnet of Pittsburgh, Pennsylvania, and Samuel J. Fleming of Wabash, Indiana, presented to the Watch Tower Bible and Tract Society the aggregate of about thirty bushels of this wheat, proposing that it be sold for one dollar per pound and that all the proceeds be received by the Society as a donation from them, to be used in its religious work. The wheat was received and sent out by the Society and the gross receipts from it amounted to about $1,800. Russell himself did not get a penny of this money. He merely published a statement in The Watch Tower to the effect that the wheat had been contributed and could be obtained for a dollar a pound. The Society itself made no claim for the wheat on its own knowledge and the money received went as a donation into Christian missionary work. When others criticized this sale, all who had contributed were informed that if they were dissatisfied their money would be returned. In fact, the identical money received for the wheat was held for a year for that purpose. But not one person asked for a refund. The conduct of Brother Russell and the Society in connection with Miracle Wheat was completely open and aboveboard.
Because Charles Taze Russell taught the truth from God’s Word, he was hated and maligned, often by the religious clergy. But then, Christians of modern times expect such treatment, for Jesus and his apostles were dealt with similarly by religious opposers.—Luke 7:34.
