Sounds like that, in order to participate in a science forum, one must have already accepted TOE. Is this accurate?
No, I'd say not. What is requied is to voice ones objections to it clearly, to explain those further when asked, to build your objections on reasoning that starts from verifiable evidence and logic.
These are, I agree, pretty stringent requirements. If it was actually possible to manage such then YEC'ers etc would be doing it a lot and even making progress in having the science changed.
However, when asked to do this those objecting don't seem to manage these things and a lot of them don't even understand the requirements.
