It's also worth noting that many companies have a global bottom line to think of, & worth noticing where their 'principles' begin & end.
So for example - I'm not in the U.K.
When M&S decided to do 'whatever you feel' changing rooms, I emailed to ask if this applied to our local store.
It didn't. They certainly weren't going to attempt this in other countries, & sent me a very fudgey response about it, to the effect that um, franchises.
So I can take my dds to try on bras in our home abroad in M&S, & be confident that they have a right to be in a female only space.
But if I'm visiting the U.K., M&S suddenly don't think that's a thing they can or should do.
Awfully flexible standards. Apparently it's transphobic to demand a single sex space in an M&S changing room in the U.K.
But in the rest of the world, it's absolutely fine in M&S to have single sex changing.
It's very hard to see any of this as other than corporate virtue signalling.
