I disagree, @Runskiyoga - using chosen, non-sex-based pronouns is an exceptional accomodation we can choose or not choose to indulge.
Everyone else in society is referred to by their sex based pronouns when referred to in the third person (if their sex is known).
If a trans or non-binary identifying person wants the society to alter the linguistic habits and traditions of centuries, individuals can decide to go along with that or to reject it, depending on their own values, understanding of gender or any other reason.
Sometimes referring to someone by their sex-based pronoun is essential to prevent harm to others, to prevent misunderstandings or obsfucation, or to retain factual information where that information matters.
When reporting on a crime, it matters. When addressing a wedding invitation, it probably doesn't.
I am happy to address my son's trans-identifying friends as they, because within my house while asking whether they will want tea or coffee it's irrelevant. If the friends wanted places on the girls' hockey team, I would say use He/Him about those male friends to make clear exactly what was being requested.
