There IS no solution, Giddy.
Having bottom surgery as it is called, does not change the law, nor does it change men's behaviour. Nor can anyone tell, so it's a totally pointless condition. Plus there really is no evidence to suggest men are at risk. Self-reported anecdotes isn't evidence
Men, all men, are not allowed in women's spaces. The solution is to use their own spaces, or find a gender neutral space.
There are dozens of apps that will tell you the nearest gender neutral toilet. It's not a secret, neither is it difficult.
Until recently women were chained to the house for bloody years because it was frowned on if they wanted to breastfeed in public.
Finding a gender neutral loo really is not the drama you think it is. There are solutions everywhere.
What's NOT a solution is opening women's spaces to men. Even vulnerable men, in your eyes. What next? old man, disabled men, feminine gay men?
Women's toilets are for women, because of our biology. They're not a solution to a problem for men because of other men!
At lastly, I don't think you clicked on that link. You just saw the front page. There are quite literally thousands of posts. Men threatening to rape 15-year-olds because they wouldn't call them women, threatening to kill women, maim them - really quite creative and vile.
The ideology attracts men like that. Take it up with them. Not the people they are directing it to.
