Just to clarify, I'd have no problem helping a 6 year old child (or any age) in a changing room and wouldn't find it an imposition at all. and totally agree that women are generally helpful but i couldn't in good conscience send a child that young in to a changing room alone and expect her to manage (i don't just mean the physical act of getting dressed) all the logistics you mentioned including getting into the shower. When my kid is big enough to say "sorry, i was next for the shower" then he/she is ready to be let in there alone.
A shy 12 year-old might not feel able to assert themselves, among a loud, pushy group. Should they not be allowed to change unaccompanied by a parent?
To reiterate, again. My 6yo was quite able to shower, change etc by herself, albeit slowly. She made a positive and definite decision that that was what she wanted to do. She did it.
The fact that women often can't help being helpful, was a separate point. At the time, it amused me, that DP wasn't aware of it and DD didn't mention (or probably recognise) it.
This fact, plus a normal ability to communicate, does offer a way round the 'where should my dd change?' problem, for any dads of 7/8 year-old girls who don't want to change in the men's. Ask a nice lady to help you. (And, with regular swimming lessons, you're likely to know some of the other parents slightly anyway).
Barging into the ladies' is the behaviour of a thoughtless, selfish, socially inept oaf and is never, ever necessary.
It takes a village and all that but not when it comes to a small girl getting naked in front of a room full of strangers - even if they are all women and boys under the age of 8.
I don't understand this. Are you saying everyone must have private cubicles, so that no child must get changed in front of other people? Small girls accompanied by a parent are still getting changed in front of people. The only way to avoid that is no shared changing rooms at all.
