What I really don't understand is, why do these people just dig themselves in deeper, lash out at their critics, when it would be so easy to apologise?
"Apologies for the confusion, I suggested the other day that exercise is good for all medical problems. It is more accurate to say that exercise is good for many, but not all medical problems"
"Apologies for falsely giving the impression that I made myself better by being positive. I would like to acknowledge that there was a lot of luck involved. I'm in no way implying that those who don't recover are at fault for not being positive enough. I'd also like to thank the people with ME and Long Covid who helped and supported me during my illness... I'm truly grateful and your advice was very valuable".
How easy would that be? But no, we gotta play the misunderstood victim, the injured party.
