I use to worship Fred Franz as a child, I was always told that he had a photgraphic memory, was fluent in over 10 languages, gave all of his talks without notes, was legally blind, and had the entire Bible memorized from cover to cover.
Now that I've learned TTATT, I consideer him just another celibate by choice religious nut job without a brain in his head. I can remember Witnesses speaking favorably of "The Plain Truth" magazine when I was a boy. His borrowing from other idiots would not be a surprise and probably happened.
