There are two things I'd like to share. One is an intensive info source/pack that has excellent topics and up-to-date info.
You'll find the It's Worse Than You Think 2009 Pack, Informational Dossier #1 – Selling Faith for Finance Is NOT a Religion; please see bullet points.
The second is a site that I have found to be excellent. It covers cult "source" on topics that relate to actual churches (ie: worship) which is interesting to Christians, Catholics, or people who don't know all the dark places the cult has made.
Catholicism (Christianity), Scientology, and L. Ron Hubbard
