In my part of the world (the SouthEastern U.S., aka The Bible Belt), this sort of thing really isn't all that unusual. Despite the fact that many protestant churches are members of such organizations (from the tiny to the enormous, such as the Southern Baptist Convention), individual congregations are almost completely autonomous, in terms of theology, "worship" practices, and, most importantly, finances. Obviously, schism is unavoidable.
Visitors to this area frequently comment to me about the sheer number of churches. Even in the smallest community there will always be more churches than the local population would seem to warrant. I like to point out how often words like "Unified," "True," or "Original" appear in their names -- a sure sign that the church split off from another congregation.
The site in question may well be a joke, but it certainly reflects a very common part of this cultural landscape.
