I don’t think you get to invoke BBT inflation

You may be right because the Bible invokes a big difference between light and stars. In the plasma universe origin hypothesis, the light begins everywhere at once and coalesces into plasma strands that eventually accrete into stars; even if there were not lightspeed decay, it seems this would account for the microwave background. But then by the same token, ultraviolet radiation would have redshifted into visible light as well. When you're getting to the range of 10 billion lightyears, you've had a chain of several assumptions to come to that conclusion and I'm not an expert on the whole series; but I do know that the experts are arguing about them, and no single news article is interested in giving the whole chain of inferences but only in quoting the scientists who assume them. For the flat-earthers, there is no evidence of 10 billion lightyears, and this opinion can be joined on many other assumptions too, as is demonstrated in the range of opinions in the "consensus" literature.

account for tens of thousands of professionals and experts who operate in these domains every day who would say your views are next to unfounded

a little more respect

Oh, I respect it enough to read it open-mindedly, but not enough to agree that it has right of appeal to authority. I'm pretty big on there being a conspiracy to cover up stochastic electrodynamics, so I hope that level of respect is understandable. But I am free to speak boldly due to the knowledge that truth will never deceive me and I have nothing to fear from myriads of contrary "experts": either my claims get backed up by the evidence, or I learn something new and admit it. So sometimes I am "very bold".
