Sigh. Another repost because I can't get myself to check the visibility level of posts...
I agree with Staniland, this is nearly Matrix-level display of dodging.
But not only does Gilly refuse to answer the question, as Staniland points out, they also are pretending that communal dressing rooms without individual lockable changing cubicles do not exist.
Now I don't know about the UK, been ages since I went and didn't spend much time in changing rooms anyway. But here on the continent and in the Nordics communal dressing rooms in gyms, pools, and other such facilities very much exist and most of the time there are no individual lockable cubicles.
This Gilly character pretending that such obvious reality does not exist and therefore Staniland's question is dishonest baiting is in itself either dishonesty or staggering ignorance.
The replies after this post are also worth reading, there Gilly pivots to "you just want to exclude Trans" instead of refusing to answer the question and pretending real conditions don't exist. And then climbing on a moral high horse over that.
