There seem to be two forms of these pronoun introductions, intended to promote transfeminism, one voluntary/declarative and one interrogative:
For an example of a voluntary/declarative one:
Kamala Harris introduced herself with ‘My pronouns are she, her and hers,’ [...] at an LGBTQ town hall.
As for the interrogative
For many faculty members, the semester begins with the now-familiar call to students to “introduce yourself with your name and pronoun.”
Have these forms of pronoun introduction/interrogation spread outside mainly English-speaking countries?
