We are not willing to make concessions for any particular theories here, our own scientific claims are afforded the same rigorous and thorough attention which we pay to the scientific claims of others.
Are you including Tom Bishop in your wide ranging statement?
The truth is, there is no standard at all in these fora, so anyone who declares himself an FE'r can say pretty much anything and the other FE'rs will not even attempt to do a peer review.
In fact, there are also some "RE'rs" here that would not pass peer review in eighth grade.
There is one thing called the Scientific Method that is taught in Elementary school and that all of you Flat Earth "theorists" choose to ignore. The phrase "rigorous and thorough attention which we pay to scientific claims" assumes you are, at least, paying attention to the scientific method, and that means models, predictions, all those things you never do.
While real scientists have made predictions in the areas of Geology and Evolutionary Biology, among others, that have then been demonstrated to be sound and give Pangea credibility, you can, at most, play with lack of evidence and try to pass it as evidence of lack.
