I'm not sure a petition is the best way to go here.
I think Esther Crawley's behaviour needs to be spelled out to her employer in a calm and rational way by someone who will be listened to.
They need to be told that she is making public accusations of harassment by patients and others who have made legitimate criticisms of her work such as David Tuller. That she is, in effect, slandering her critics.
They need to be told that she is giving talks to other doctors encouraging them to hide their data and refuse legitimate requests for information, and to treat these as harassment.
They need to be told she is using words like drug addiction (correction 'substance abuse') and crime in her descriptions of ME patients, and alongside these words using photographs of people that she has no right to use and who have nothing to do with ME.
They need to be told also about her appalling slurs on ME patients and their parents, especially mothers.
They need to be told about her unscientific research methods and anti-science behaviour, and that she is going around telling sob stories making herself out to be the heroic scientist standing up to harassment.
They need to have their eyes opened to her whole unprofessional, slanderous, unscientific denigration of and mistreatment of patients.
They need to be told that she is carrying out research of such poor quality that it will bring herself and Bristol University into disrepute, as PACE has done.
I don't think a petition would work to get a complex message like this across.
Do you get the feeling I'm a little bit angry...
