Surely we are not bound by law to refer to people with GRC as their chosen gender in everyday speech, or casual correspondence?
Or when talking about a group of those with GRCs or an individual in general conversation in any context as opposed to having direct conversation with someone who is present?
Isn't this what Maya's case is testing? The difference between a legal fiction which must be recognised in situations such as employment, and compelling speech against the beliefs of the speaker? The difference between courtesy supporting of the chosen legal fiction with pronouns in individual conversation with a GRC holder and in general situations such as a work place with them, and being expected to state in all contexts, at all times, even in theoretical conversations when debating harm to women's rights, a belief that a male person is a woman? For a legal context to recognise as unacceptable (as the judge in Maya's case seemed to try to do) for a woman to state out loud that she does not hold a belief that a male person is a woman?
In essence, the right to hold a view that some may find offensive and disagree with which applies to everyone, equally, regardless of any protected characteristics being involved , without this being a criminal offense.
