YoYo, I've read the Proclaimers book thoroughly. Go to Randy Watters' website, http://www.freeminds.org and look for a critique of the book. I wrote it in 1993.
As for this researcher, if you call me on the phone I'll tell you all about it. But we can all see how you're playing games here, doing everything you can to avoid actually dealing with the truth. You invent reason after reason to avoid answering questions and to avoid seeing what you don't want to see. This proves that you're afraid, deep down, that you'll confirm what you already suspect -- that "The Truth" is not the truth.
