I think that many of us have noticed the presence of Professor Danny Blanchflower on Twitter. He is an old friend of Professor Peter D White and has been aggressively defending the PACE trial. He uses abusive language—for example calls patients with ME/CFS “whiners”—and quickly blocks people who asks uncomfortable questions or make good replies. There is another person, James David Chapman, who acts on Twitter. He is a patient and former ME advocate, but seems to have been hurt badly in the debate and now says that he tries to stop abusive behavior. Although I think there is some merit to his claim that the debate can sometimes be overheated and that there are too many ad hominems, he has a strange way of advancing his cause. He writes numerous tweets where he unilaterally blames ME/CFS patients and advocates for the hostile tone and represents all BPS researchers as victims. If he is challenged, he refuses to engage in debate. He doesn’t block opponents; he just writes aggressive tweets where he says he wants no further contact. Ironically, the tone in these tweets can be perceived as abusive. Blanchflower and Chapman have now started to interact. That means that they have created a protected arena on Twitter where they can perpetuate negative stereotypes of ME/CFS patients and advocates, but no one can challenge them because they are either blocked by Blanchflower or rejected by Chapman. What is the best strategy to deal with this? Ignore them? Tweet about Blanchflower, even though you are blocked? Should you respect Chapman’s requests that you don’t reply to his comments, or should you simply ignore him and reply anyway?
