So Christians are now fringe
You know exactly what I mean. There are traditionalists and there are fringe fundamentalists. A good comparison is the FLDS group to the overall Mormon church. These are the types that think the eclipse is a sign of the end times and read numerology type books (although not called that) looking for hidden prophetic codes and the ilk, or think they can 'will wealth' through some magic faith power (name it and claim it). Looking at the pages of the person Bachmann was interviewing with, it definitely fits into that latter group.
Maybe a more appropriate word would be heretical.
