You don’t address (speak to) a person by their pronouns. The pronouns by which you address a person are “you,” “your,” “yours.” They do not have genders.
The pronouns they meant to talk about are third person pronouns, such as “he,” “she,” and others. They are used to talk ABOUT a person, and are not used to address a person. Elementary English Grammar, logic and common sense.
There is conspicuously very little logic and common sense today in the “public discourse.” There is an enormous amount of base emotion, hysteria and ignorance.
From the court case:
On the first day of class, Meriwether was using the Socratic method to lead discussion in his course on Political Philosophy. When using that method, he addresses students as “Mr.” or “Ms.” He believes “this formal manner of addressing students helps them view the academic enterprise as a serious, weighty endeavor” and “foster[s] an atmosphere of seriousness and mutual respect.”
A good answer, and nearly a very excellent one. As you say, an elementary one.
“Thee” “Thy” and “Thou” are the traditional second person singular English pronouns, and they are not gender specific. Neither is the second person plural, which has nearly obscured the singular, in imitation of the Romance language honourific forms of address.
Thus, if a person wants to have specified pronouns, thou should address him (traditionally in the third person, the masculine was used to cover the neuter, not “one” or the even more barbaric third person plural) in the Quaker fashion, and ask him to do the same, so that one thou is speaking with him, he does not confuse thee in thy speech.
