Oh but there is an implied value - superiority. When you give a group of people a descriptive property with no inverse you are basically creating a construct of "assumed default". This comes with other issues of those falling outside the default having no way to effectively talk about people of the assumed default group without using words that have value judgements baked in. Like if I am calling you "a normal person" the implicit value judgement is that I am an abnormal person. I am "othered".

This sort of denial of language assumes that a group that you are given tools to talk about never and should never talk about your group back utilizing those same tools.
