The evangelical supporters of the bullshitter are crazy religious
fanatics. The author's conversation with his mother illustrates that

In their fervency, they overlook the fact that their scriptures do not
say that the hoped-for second coming will occur in the next century or

religion. Perhaps they would conclude that preserving everything the
Earth's ecosphere is consistent with their religion if they are
hammered on that one point.
