What I have found, and a lot of on CZ, is the dismissal of anything that even involves the word 'science' or 'scientist', and anyone who promotes research, (even simply doing your own research), to verify claims made by alternative practitioners, is branded as a shill, agent etc.
Yes, I agree. And I can see why. If we start showing that many alternatives have been studied and proven then the alternatives with no studies look bogus. And since they cannot justify that their particular claims, such as those for "liver flushing", have no evidence to back them they just reject all studies as bogus so they don't have to justify their own lack of evidence. An all or none attitude.
