Some people should take courses in logic and formal thinking before making claims. But maybe that's overkill, since these people probably wouldn't apply what they've learned, and instead would continue with their knee-jerk reactions.
Like Dr. Behnaz Yazdanfar, a Toronto-area medical doctor who isn't licensed to perform surgery in any hospital but performs cosmetic surgery out of her private clinic. Recently she was in the news because one of her patients died. Yet she is suing plastic surgeon Dr. Sean Rice for slander, claiming his comments to patients is ruining her business.
Now slander is a problem, one of the few cases where I support limits on free-speech. But you have to wonder why Dr. Yazdanfar is seeing so many patient cancellations. Is it because her competition is telling (new) patients that she's not qualified (she isn't), or because they are telling the patients that certain breast-implant makers won't sell implants to unlicensed practitioners (true)? Or maybe her patients are cancelling because they read in the paper how her patient died? I dunno... seems like a complex issue that requires a lawsuit to straighten out.
