It's a slightly odd opening post.
I see that you are new, and maybe haven't read the numerous threads on here with specific examples such as the ones on this thread.
It's partly about those specific examples. But as you say it won't affect everybody, all the time.
What will affect everybody, 100% of the time, is that their rights will disappear. Whether they exercise them or not. Their choice will be removed.
Some of those are rights enshrined in law and some are customs and protocols that have the effect of 'rights'. (The right to challenge a man if he is not where he would normally be).
A man in a female intimate space has to do very little to intimidate. The lift of an eyebrow, a concentrated look, a smirk. That's all it takes. No laws broken, nothing you can actually hold them accountable for.
And women, culturally and socially will have to accept it.
Why? Why should we change all the protocols about sex segregation, to validate a handful of men?
Seriously. Tell me why? Who benefits? Tell me a single woman who would benefit.
I also have a question.
Quite apart from your common or garden predator/voyeur/peeping tom/paedophile who can exploit this with ease, here are men who fetishise women and their biology who are officially transgender, under the Stonewall definition.
Men who become aroused from not only accessing women's spaces, but by forcing them to accept that they are women.
And who enjoy women's discomfort at making them use the correct pronouns and the correct name.
Men who are compelled, by a sexual motivation, to access as many women's spaces as possible.
My question to you, is if these men are officially transwomen, how can we tell the difference between them and a transwoman with gender dysphoria? And, why should we even need to?
If you haven't come across autogynephilia before, perhaps this thread will help you.
