Hmm, I don't know the exact political situation in the UK or in the US. It is highly confusing, what I got, that some advocacy and charity organisations strictly oppose the BPS and some go partly along.
I think a compact letter signed by respected doctors and scientist would be a good idea. Fortunately, the last couple of years gave us some hard biomedical evidence for abnormalities in well conducted studies. We should use that. Maybe a letter should explain in a short and precise way those studies and findings (like CPET, Rituximab, Cytokines, Leptin, POTS and OI etc.). The hard part is, that we still don't have a final model of the disease. A lot of speculation wouldn't bring us anywhere. So why not sticking to the hard facts of the studies conducted.
Another problem is, that all the ME advocacies and patients groups are still divided in their efforts. If we could create an international advocacy site, just for the patients, supported by a lot of different ME groups around the world, we would have an immense resource for future crowd funding and awareness campaigns (I think, Jennifer Brea thought about such a page, if I remember correctly). Imagine such a page would have 20.000 members from all over the world. It would be a lot easier to start new projects. But it seems to be a huge amount of work. On the other hand, crowd funding for medical studies is a completely new idea and it already worked very well.
The internet is the perfect tool for us. The question is, how to use it in the most powerful way.
Just some ideas with a huge brain fog.
