Upton's perception of self is like the dualism of Rosa Parks. The common public perception of Rosa Parks is that she's a woman who just got fed up going to the back of the bus and made a stand on that day, sparking the bus boycott.
In reality, Rosa Parks was a very astute political mind with an outstanding record as a community activist. (Excellent Theoharis book, I recommend it. I've not seen the film.)

I see the self-presented, waif presentation of Upton. I also see Upton's self-assessment as a political operator. The response to the consultation is Jan 2024 or around about the time when Upton was still 'traumatised' from the Christmas Eve 2023 CR incident (if I understand this timeline correctly) and the sequelae.
I think the NHS is motivated to use this tribunal to assert the implementation of mixed gender facilities everywhere. This is absurd, because they'd be excluding anyone with a conservative faith that forbids this. But, as we've seen, the NHS' strategic thinking only extends so far in some areas.
