I am also a grandmother and on the MN feminist chat. It's clear that lots of people on GN don't really get what's going on with this transgender stuff. It is not about people with gender dysphoria, struggling for years, having physically & possibly emotionally painful surgery to transition, a life time of hormones, then not being welcome. That is the old model and it's almost obsolete now.
There is a plan to change the law so that anyone can self identify as the opposite sex, get a piece of paper saying so, change their documents to reflect this and live as a person of that new sex. All the current gatekeeping will disappear. However, because it will (it is believed) be illegal and certainly unwelcome to ask for proof of this change, the result will be that anyone can do this. Yes, it applies to women 'changing' to men too, but that is not my concern. I am concerned about, amongst other things, women's and girls' dignity, privacy & safety.
Imagine this scenario: you go to the ladies in a shopping centre or anywhere. There are 2 men in there, just hanging around. They are clearly male: beards, clothes whatever identifies an adult male human. You say something like 'I think you're in the wrong place, the gents is down the corridor' and they say to you 'we identify as women. We are allowed to be here and you can't do anything about it'. What do you do?
Every cell in my body would be screaming at me 'DO NOT TAKE ANOTHER STEP INTO THIS ROOM'. So I would turn around and leave, ignoring the state of my bladder. If those men knew who I was and I could be traced, it's possible I could be found by the police and interviewed under caution for a 'hate incident'. Because those men have 'identified' as women and must be treated as such.
What would you do or tell your daughters/granddaughters to do in this situation?
