Sheldrake was banned for talking about what the materialist/naturalist/determinist religion call "pseudoscience". But he's using the exact same scientific method that they are.
& people who have been banned who really were crazy (eg alchemists)
But just the fact he is banned is not evidence he is correct. There have been people who have been banned & been correct (eg galileo)
It's not weather he's "correct" or not(technically there is no such thing in science, only evidence). He was banned for questioning authority and asking forbidden questions.
