I looked at their materials in detail. It is a classic anti-Mormon site, with the intent to draw people away from the LDS Church and “educate” non-Mormons to keep them from joining. Some of their claims are more than a little disturbing, to say the least. Others are quite simple and, in my opinion, no big deal – like which day ought to be celebrated as the Sabbath.
