I'm glad PG's better, and really hope it's true he is, and it's not just the LP tell everyone you're better / fake it till you make it... And while i do think he bears some responsability for what he posted, and I was very hurt by what he wrote, I also think the BMJ bear responsability as well. PG has had an increadibly traumatic experience this year, as many of us have also experienced when we first got sick- the illness is horrific, and it is terrifying, exhausing, confusing. Constantly confronted by Medics who not only don't know how to help you, but don't even want to try, and who are often abusive as they dismiss you. And for him, with the added stress of his illness being part of a global pandemic, scenes of folks in ICU, 100,000 dead already, knowing that could have been him.
In a best case scenario where the BMJ is an instituation that acts with integrity (

bear with me...), they had a duty of care to PG. If I was an editor reading this for the first time, i'd be asking very specifically what had caused this complete change (in his health, in how he writes and in how he presents himself), and when he explained about LP etc... as a scientist, i'd be really very concerned for PG. His welfare and health should trump having an article to put on my website.
In the real world, we know BMJ is ethically challenged in too many other things. We know they know the history of ME, PACE, GET and know all about what LP really is. They wouldn't even have had to ask. It looks like they threw PG under the bus: all for ratings and page clicks and furthering their agenda. win - win for BMJ, but what about PG? After the backlash, are they supporting him now? (Not that that would be a good thing in reality... I hope he has some good friends or family who will hold him through this thing he's stumbled into.)
I agree with most of the comments made on what he wrote, and don't have any issue with him being challenged on science and theory, which is what the majority are. But, also, at the same time, he's been through a genuinely traumatising situation. I'm not saying people who've experienced trauma shouldn't write or be published, just that there surely has to be a duty of care from anyone benefiting from his stories of trauma. No?
