Descriptivism isn't the be all end all of what a word ought to mean. The easiest examples are slurs. For example, it doesn't matter if the vast majority of (cis) people do not consider the t-word to be a slur because frankly, their trash tier cis opinion doesn't matter. All that matter is trans people prescribe the t-word a slur, and whatever trans people prescribe it so, then it is so.
