The reason FEers cannot accept the plethora of flat maps is because doing so would invalidate FET. You see, they are leading the data, not trying to find the most accurate model.
It's been my experience that the reason that the FE community can't accept a map or model is because the individual beliefs about their own individual flat earth model vary so greatly. As an example:
1. I had several people tell me that the earth is a flat infinite plane. Anything that shows the earth with an edge or end is instantly rejected.
2. Some people believe there is no ice wall and that some sort of dome/firmament is at the edge of the flat disk earth. Any map with an ice wall is instantly rejected.
3. I had a few people who had a more biblical flat earth model say that Jerusalem is at the very center of the flat earth. Any map not depicting this is instantly rejected.
4. According to one person this was the most accurate map of the earth based on a very specific set of flight times (ignoring flights to and from the round earth southern hemisphere because they are fake). He would reject any map which is different than this:
5. The same person from number 4 also debunked his own map by claiming that, because japan has more seismic activity, it is on the edge of the earth.
I believe, based on my personal experiences, that only about 40% of the entire flat earth community believes in a flat disk, ice wall, no dome, no firmament, north pole center model. At this forum I believe the number is closer to 70-80% because the community is less friendly to alternate models.
Even though a flat earth model such as Bing maps would be much more widely accepted among the round earth community the flat circle model will never go away.
