Frankly I can't understand why some people are seeing that as somehow undermining the very existence of mold-related illnesses, or their specific situation. Though I suppose it's easy to get invested in the HLA theory if that's been the basis of someone explaining their illness to others. But sometimes we just have to accept that we don't know "why" yet, and just focus on fixing what's going wrong.
I absolutely agree with your last sentence. As for the other part, I don't think it's the matter of shaking one's belief in a treatment that's working; anyone who's benefited from avoidance or mold treatment knows it's not just in their head. Nor do I believe it's the fear of losing a scientific explanation to convey to the outside world. Also I didn't notice anyone on this thread stubbornly insisting Shoemaker's work is solid. I think those of us sticking up for mold treatment do so in hopes others who might benefit won't be persuaded away from it.
It's kind of the same with CBT. Sure we can infer the intentions of the authors of the PACE study, but they're not explicitly saying the disease is psychosomatic. Yet we fear the tacit implications. And on the other hand when the science of the study is rightly called into question, do we throw out CBT as a viable treatment? Will our community be more likely to shun it because of the negativity it gets on this forum? That wouldn't be good.
Some of us believe published science is the only solid thing we can rely on to further our understanding, but when it comes to treating ME/CFS, it's unfortunately still, in my opinion, not all that helpful. Science-based medicine can be a real tyranny when it's used to malign bonafide treatments not firmly backed by its discipline. Many without the sophistication to understand the limitations of science may end up postponing helpful treatments, thereby suffering unnecessarily for years. Perceptions are really important in this disease and the stakes are high. Personally, I wouldn’t want any part in prejudicing a sufferer against a therapy that might spare them years of anguish.
Most on health forums do understand the value of cumulative anecdotes and can properly weigh that against hard science. But others, mostly overwhelmed newcomers, are less able to do so. And I'll confess I also worry about those veterans seduced by the dark art of science-based medicine, too.
It pains me to see very intelligent people studying the minutiae of the hopefully relevant literature but never actually getting around to trying things that might help.
