The thing is what happens in USA isn't rocking boat in uk. It isn't just the PACE authors who won't want to u turn , but the journals, the NHS, the press like bbcs tom fielding who's presented the ilness as psychiatric and who've revelled in the "controversial illness /militants patients narrative '. No ones going to want to admit that the MRC and NHS and themselves had it wrong and that those Whiney people they were advising to exercise were actually very sick with legitimate grievance. And even the current head of the royal colleges of psychiatrists was actually completely wrong.
It's like the church can't admit the Bible is wrong on homosexuality because then their and it's authority is diminished and up for question
Who really runs the NHS? Do they benefit from real treatments?
If the medical establishment push the phony narrative that ME/CFS is all in the head, who benefits?
I think we have to be very positive, but also be aware of more sinister goings on. Ice Cube said it best.
