Someone looking at my bookshelf and rooting around my garage would find an English-language copy of the Koran, several books by skeptic Bart Ehrman, a copy of the Book of Mormon, and copies of almost every Watchtower hardback book published before 1980. But I am not and never have been a Muslim, JW, Mormon, or whatever Ehrman considers himself to be. Sometimes you want to understand the views of people with whom you disagree.
Personally, I suspect the late unlamented twit was more than a little "off", so crazy is part of his mix.
