Whenever semantics comes up, an initial response could be what do you mean by that, or are you trying to be mean? News or Views?
Ancient Greek: σημαντικός sēmantikós, significant is the study of meaning, reference, or truth. The term can be used to refer to philosophy, linguistics, and computer science.
Semantics can mean quite different things in different contexts; fields concerned with semantics are as diverse as psychology, law, lexicography, and logic. Pragmatics is an equally wide-ranging term, with applications in politics.
This term could be the confusing situation society finds itself in. The suggestion is for everyone to mind their words, including P and Q.
Sometimes things are said without giving much thought to the tru meaning, or as a result of different points of views, or version of reality as we see, or remember them. The best practice is just to stick to the facts, and not inflate them with our opinions, or augmented versions or enhanced recollections.
