It is common to be asked to "share your pronouns" at the start of meetings. People who do not accept gender ideology think a person cannot choose his sex/gender. To such people sharing pronouns is an affirmation of a false anthropology (a lie). Does that make sense?

About your aside, your understanding is now out of date. Within the current incarnation of gender ideology, gender has become reified, rendering gender and sex equivalent. So, for example, it would currently be considered incorrect to refer to a man who claims that he is a woman as a "male" within this ideological framework.
