I'm not sure I understand what you mean with this. Is it that you aren't objecting to the MEA posting it because you don't consider it as bad as a BPS research paper? I would argue that, in many ways, it's worse, especially where we are with the NICE guidelines. BPS papers can be shot down by looking at their scientific methods, yet here we have one patient organization supporting exercise therapy and the Lightning Process, and a larger, more influential, patient organization, who have actually previously argued against both therapies, have now implicitly endorsed the article, and therapies contained within, by sharing it.
It weakens any argument the MEA makes against physical therapy and the Lightning Process, it's a politically silly act to take.
