No, the point is to use somebody's preferred pronouns once you know them.
My complaint is the GNU guidelines explicitly allow you to not correctly pronoun/gender somebody, once you know their gender identity.
Re non-native speakers, etc, all I am criticising is transphobic intent. People are, of course, allowed to slip up. Hence my use of the word "persistent" in some of my posts: I mean persistent and deliberate.
