No, that is not it all. The anti-concept is created for the purpose to deceive. It is not using a nuanced or alternate meaning but an anti-meaning to the word. As I said, the Progressives/Socialists have been adept at this ...
If you reject the word as well as the anti-concept for which it is used, you make it impossible for me even to ask where the deception is in the terms 'prescriptivist' or 'descriptivist', which makes it hard for me to learn to what you are objecting. What is the deceit or false claim? What is the lie?
Remember too that assumptions and beliefs are bound up in terms (e.g. human being/human life). You may reject the beliefs and assumptions, but you will never convince anyone if you so completely reject the words that you will not even name them to refute them. You will never even succeed in telling people what you do believe.
All of this is my belief and opinion, and perhaps my limitations. But my limitations are part of who I am, and if you mean to communicate to me, you will most likely succeed if you communicate to who I am, rather than who you would like me to become.
