Matthew Wright handled it well, constantly dragging the contributors back from personalising it to principles, but some of his observations (there was some nonsense about people in family homes sharing lavatories with members of the opposite sex) seem off-key. Is he lobbing stuff like that in because he needs to be seen to try to be neutral?
He used this argument many times in his TV show. When Terry Christian replied "but not at the same time", he looked confused as if he didn't understand Terry's point. I think he sees the stalls as an adequate safety barrier, and thinks women are complaining about having to use the same facilities as men, rather than at the same time.
I think the focus is on 'bathrooms' for a number of reasons, one being as they are seen as somewhere women go in pairs or to do their makeup, so exclusion from loos makes transpeople 'gender refugees' (I've seen this term a few times over the last few weeks and it's appeared on MN recently). So by being excluded from toilets, they are being excluded them from an essential part of a women's life 🤔
Changing the focus to other issue - safeguarding, the need to encourage girls into certain careers is proving difficult, but will need to be tackled eventually, even if tra succeed in removing female loos.
