Let us please remember that the timeline of FE is much longer than that of RET. This makes terminology to include everyone interested in RE be properly referred to as round Earth "believers".
Would RE believers even dare propose this causeway anomaly as a purported problem (understood by others and explained by FEers) to Jesus of Nazareth, Christopher Columbus, or Albert Einstein?
Case closed.
Yes, the timeline of FE is much longer, yet RET, with its much shorter timeline, is capable of explaining so much.
Yes, RE believers would propose this causeway anomaly as an issue if FE garabge was the accepted theory.
Remember, this is effectively what happened in the past.
FE was simply assumed with no rational basis.
People found problems with that and raised questions based upon these problems.
This led to people realising Earth was round.
So yes, case closed, Earth is not flat.
And no, FE being around for longer does not mean all REers should be referred to as believers.
RE, being a model which matches reality, which is widely accepted makes the REers normal.
As such, it is the FEers that are special and should have a special title.
