It's curious how politics and activists tend to approach definitions backward. Anyone who aims to be rigorous (as politology and sociology should be) knows that you first must define clearly a term and then reason about it. Instead, we usually see attempts to redefine well-established terms, not by adding an additional meaning, but by replacing the original one. In a purely rational reasoning system, this change would be irrelevant because the important thing is the meaning, not the significant. But we humans are fallible beings, and we tend to transfer the perceptions and logical conclusions attached to the meaning to the significant itself. This way, when a redefinition is done in a society, the term will drag for a while the concepts related to the old meaning. This is a powerful manipulation weapon and I think it's the reason why it's so prevalent in those fields.

This is not saying that you shouldn't redefine anything. As you said in our daily lives there are a lot of terms that have lossy definitions that don't match perfectly with our mental models. But you should be cautious with the real intent of the redefinition, especially if it comes top-down.
