You’d think so - however it seems trans women don’t like using a third space toilet as they ARE women and therefore have the right to use women’s’ toilets.
India Willoughby tweeted about how he refused to use gender neutral toilets in Manchester Airport and went off in search of the womens. His tweet was supported by other trans women who said they did the same.
It’s not about the physical toilet as I naively once thought. It’s about infringing on women’s rights.
