MrsMcGarry your argument just seems to be that you (and women like you) don’t see your rights as threatened by self-ID and therefore the problem is not a significant one.
For those who do see their rights as threatened, the problem IS a significant one.
So, you would need to explain how my (and other women’s) rights and existing provisions are not threatened, to convince me.
I just spoke to my mum, aged seventy-one, about this. She is not a conservative person at all. She said she would have to give up her ladies’ gym class if there would be non-female people there when she was dressing and undressing, because she would not be comfortable, if self-ID went through. Why do her rights to same sex changing facilities not count?
What about when I have got my period, and I am flooding everywhere, and I need to shout to my daughter to get my handbag from the restaurant, or even worse, miscarrying on the bathroom floor? What about the thing I have mentioned before, if I did not get a female bodied rape counsellor?
You cannot self-identify as a gender, because there is no such thing as gender. Gender is the set of social rules and norms we apply to each sex. We can and should expand those gender norms, but not at the cost of erasing biological reality (sex).
Just because you are cool with all that, it does not mean that other women should be, or that they are wrong. Their concerns should be listened to as much as any trans identifying person, regardless of what you personally think. It’s great that you are not bothered by the prospect of self-ID, but that does not make it a non-issue.
