You obviously haven't focused on the Religion Forum either, especial in 2007 forward.
I follow latest posts every day and I’ve read a lot of religious debates. I can’t say that I’ve seen on FR a phenomenon of people pushing the Mormon religion. I’ve read many posts attacking the Mormon religion.
The times I got involved in the Religious forum, it was always an article warning about Mormonism.
Just letting you know my observations. There could be a zillion pro mormon posts but then again the reaction of the typical consumer is often valid. As a constant consumer of FR I’m aware of a trend to express concern about Mormonism. It’s definitely not my issue.
