Please name a scientific theory being "shut out".
Let me see if I can help. Who said scientific theory? Using the lingo defined by the establishment makes no sense. Shutting out the free exchange of ideas is what I said. Have trouble reading?
Theories are defined and promoted by the scientific establishment. AS such, I prefer to use "free exchange of ideas" a term which is more all encompassing and allows for a vastly more broad scientific playing field and field of inquiry.
