There is a lot of harm in diagnosing others (and self diagnose) over the Internet and in real life in absence of actual medical diagnosis. It could be harmful in many many instances.

We all do it to an extent of course as it could be tempting. But some people throw around diagnoses and symptoms (not obtain through true medical knowledge or any kind of real education but just random stuff they read on the web or see on you tube) so excessively that makes one wonder why they do it? And often it’s not even about people they know or have ever met. Just random speculations

Yeah I wish people stop doing that. It’s wrong on all levels
