I have a way around the valid worry about people reading the littera-trash and becoming witlesses on it. If you prominently put an apostate web site on the book as a reference, chances are good that they will read the littera-trash and then go to the apostate web site. That should turn them off from the cult permanently. The apostate web site should be prominently written down on the very first page of the book, and again under the Table of Contents, so they cannot reach the "do not read apostate material" part before they see the web site.
