In my opinion
@JoanDublin pieces like that are always undermined by claims that aren't particularly rigorously referenced. What this allows is the very valid points within the synopsis to be dismissed because someone is adding in stuff that they can't actually support with evidence.
It's my understanding that we have many potential biomarkers, but none that definitively point to "yes, you have this illness".
In addition, using the term retrovirus with ME/CFS is also quite unsubstantiated, despite some people reporting successful improvement in symptoms when on anti-retroviral medication.
I also wasn't aware that Jen was taking two anti-retroviral drugs, though I could be wrong. I was aware that she took Valcyte as well as some other treatments.
I don't think it should be Jen's job to take people on in this situation. She has already effected bigger change and awareness than years of advocacy through her film. The average listener will likely not hear someone who's standing up to someone who's part of the problem if she did go in all guns blazing, they'll hear someone spouting slightly fringe viewpoints to a respected doctor. And from that, no one is converted, and ME/CFS patients are easily pigeonholed as catastrophising and militant. She didn't back down, she continued to state her points plainly and rationally.
