As site owner I would like to step in here with a few words. I encourage frank discussion, and I encourage doctors to participate as long as they declare themselves to be doctors (which declaration HONcode have now made a condition of their accreditation, and thus it is now a condition of registration and participation on the board), and I do not have any problem with anyone participating from a purely academic perspective. I also encourage other health professionals (ie non doctors) to declare themselves, although it is not a condition of registration.
I locked a post this week because of the unpleasant tone of the conversation, because I have no interest in owning and moderating a bulletin board which is just a venue for people to attack one another.
So please just keep the tone of conversation professional, including any private messaging.
