I saw a thread recently where several posters repeated the same medical misinformation. I have also read diet and exercise threads where some posters dish out their own opinions as absolute fact with the air of being an 'expert' on the matter. Just now I saw a thread where a poster mentioned, apropos of something else, that she has a glass of wine with dinner every night, and several posters told her, very seriously, that she had a drink problem.
AIBU to think that some posters actually do more harm than good by trotting out this vaguely medical type misinformation - either scaring posters, putting them off making healthy changes to their lifestyle, or misdiagnosing because they actually haven't a clue what they're talking about?
