Yes, I remember this NWO stuff as being popular with fundamentalist Christians. I think it’s a different beast (pun intended) though.
IIRC, the Constance Cumbey NWO view was concern about syncrestic Christianity (Unitarian Universalists, Unity Church of Christianity, and this notion of a “christ-consciousness” rather than an actual Messiah), rather than an economically directed NWO of people who want to remove choices from the world population, minimize the actual distinctions and perogatives between and of nation states, etc.
In my experience, poorly educated people who are very religious tend to be very conspiracy theory prone. Regardless of what religion they are. I will guarantee you that the measles outbreak among US Somalis has something to do with some rumors about the nefarious intent of vaccination (and nothing to do with autism).
