The intent from the creationist position here is to use the extended synthesis to declare the theory of evolution dead and slander anyone that accepts it as some sort of religious believer. If you do not think the modern synthesis requires replacement you are doomed to be labelled dogmatic. If you do accept the extended evolutionary synthesis, then you are doomed for jumping blindly from belief in one theory to the next I suppose.
There are many reasons why the EES has been proposed and many reasons why most do not accept it. All of these that I have read are based on evidence, how that evidence is weighed and where one places a perspective with regards to a genetic or organismal basis. Acceptance of the current theory based on the evidence does not render a person a dogmatist. Both are scientific, using evidence and logical argument. The creationist dogma all boils down to the "Default Paradigm" Declare the theory of evolution dead and whatever belief desired becomes the replacement by default. But no rational person is going to accept the declaration of some random poster on an internet forum as the final say in the acceptance of a scientific theory.
The facts of evolution exist. Darwin's original theory was formulated to explain those facts. In the mid-20th Century, a revised version of the theory (the Modern Synthesis) was formulated to include new information on population biology and genetics. The facts of evolution remained and many, many more had become known at that point. If the EES survives to become a new formulation of the theory of evolution, there will be even more facts for it to explain. Clearly, creationists equate the facts of evolution and theories of evolution to be the same thing. Kill one and all the facts are scattered with it by default. But we were still held to the Earth when Einstein came along and upturned Newton's theory. It isn't as if we all suddenly flew into space. And we still use Newton to this day, despite it being incomplete in comparison to Einstein's.
It is ridiculous to consider such an irrational position in light of the evidence and the explanatory power of theory. I know that some people are simply ignorant and don't know enough to properly evaluate these things, but some know enough to know what they are doing and the ethics associated with that effort. It would be difficult to convince me otherwise from what I have seen of wordy mantras placed in heavy rotation, declarations of a win that hasn't happened and passive aggressive defamation. That is the chess we all see played here.
