> Obviously, physically damaging one's body works as one line - a line - for physically harming someone. Surely you can see how radically different this is from so called 'emotional harm'.
The idea that emotional harm doesn't involve physical (even if not structural) damage to the body requires that emotions exist in a non-physical realm rather than being epiphenoma of physical states of the body.
The idea that so called emotional 'harm' cannot involve physical changes is not assumed in anything I've said.
The important thing here is that it is easy for reasonable, practical people to agree on what constitutes the act of physically harming another. Your own statement demonstrates that it is not so easy to draw a line on what constitutes 'emotional harm'. Which structural changes deserve the label "results of harm" ? The innate slipperiness of the concept is exploited by those who wish not only to 'protect' themselves from hearing unpleasant opinions, but also to elevate the act of silencing others to a righteous form of 'protection from harm'.
