Bad judgement by the organizers. A request to focus a presentation within certain parameters of the meeting plan and objectives would be reasonable for such an event, but an outright ban is a sign of both ignorance and insecurity. There are many things you’ve said or written that I don’t believe are accurate, but I fully support your presenting your ideas and conclusions to a free and open “marketplace of idea” to live or die on their merits and the capabilities of listeners or readers to do their own verification. The world/universe is big and complex. What living person knows it so well as to flawlessly distinguish among objective observations/measurements, hopes, dreams, fantasies, revelations, hallucinations, delusions, and adequate unbiased proof? Decentralized, open-source debate and collaboration is a good place to start.
