Flights of fancy?
You have said that you would never share with a stranger of either sex which is your choice but you have to realise it is extreme. Young people can and do travel around, loads of the time, all over the place. I certainly did when I was young, and my friends too!
The issue as ever is also not likely to be "trans people" but they allow for anyone who says they are a woman in with the women. This is opening the system up for abuse.
Many women- especially younger ones - 16 / 18 /22 whatever would be much less likely to complain than older women.
Older women who are more likely to complain would likely be asked to leave themselves.
It is not a flight of fancy given that many organisations now go on self ID - irrespective of the equalities act
And that some of the more extreme TRAs are seeking out single sex facilties to "test" whether they are "trans inclusive" and then clobbering them on social media if they are not.
If you have decided that this policy is not a problem after all then that is a pretty quick turnaround. So the idea is that you don't think women should be offered same sex, and given same gender ie could be in with a chap,
But as soon as the conversation takes a turn you don't like - or maybe there is a poster you don't like - you change your mind? And say oh well it's only 6 months and I wouldn't share with a stranger anyway and it's very unlikely so actually it's not a problem after all.
