TLDR If I get arrested for being topless as a trans women the outcome would either be
1: it’s illegal, which would be a win for trans women as we would be considered closer to cis women, or
2: it’s legal which would be a win for free the nipple movement because it could be argued “that trans women can do it and their boobs are the same as ours”
The push for the rulling was that the word “woman” in the equality act, should apply only for those assigned female at birth. So they would have to use their assigned at birth gender. Do note that they only ever shouted loudly about trans women, never that a trans man would be using the mens instead.
I’m too rash to live in such difficult times. I just want to gather a mob of terrifying trans men and hit up women’s bathrooms, but I don’t think that’s how we maximize rights.
not quite, the ruling explicitly didn’t make it as simple as that

In other words, they want you to pee on Thatcher’s grave instead!
