"Not viewed as a researcher." I read as far as that on your comment on Dr. Clark. Your circle of reference must be the circle of acquaintances in the medical field with whom you are endeavoring to discuss/start your Liver Flush project. Is the only way to get that project started is to have to agree on their evaluation of Dr. Clark's work? (I am wondering about the peer pressure factor.)
I do not share their opinion on Clark's work nor your emotional connection with them, however it may be. I would ask them to see what the definition of "researcher" was in the French dictionary. It's not that different any place else.
