This is exactly what it was like when we got our 18 seconds of (slanted in our favor) church history presented to us in Bible institute. It was enough to choke a goat.
One of my clearest memories was that a guy who ran an inner-city ministry to drug addicts was invited to speak to the student body at our daily chapel service. He was an impish, mischievous sort, and he opined, while the president of the school visibly squirmed in his seat, that many of us were going to be astounded at the people who were allowed into heaven with us. He delivered a message of inclusiveness and compassion that I had never heard in a fundamentalist setting before. Let's just say he was not invited back; it suggested that a lot of that chart in the cartoon was worthy and enlightened, too. In short, it promoted epistemological humility, at least intra-church humility.
Fundamentalism is predominantly rural and suburban. When it occasionally goes urban, it is quickly confronted with reality. The result is that they either retreat to their safe enclaves or become something not-quite-fundamentalist.
If you look at the depiction it looks much like a "tree" you see in taxonomy. That is the evolutionary tree of life so to speak. As a historian of early Christanities I often say if you want to undedrstand evolution study religion.
The funniest part for me is how much the diagram resembles an evolutionary "tree of life"...
Maybe that's where the idea came from.
Hero with a Thousand Faces - Joseph Campbell
I had no idea that was from 1949 until I looked it up just now.
