It’s also incredibly odd and dysfunctional, Stevie (since you’re here), to build an ‘Annihilation machine’ in order to create a world in which you are always right, because you set all the rules and alter them if anything doesn’t work the way you like it. Are you a gamer by any chance? (Also… multiple pages? Your post is longer than this thread).
To coin a phrase, I just want to pee (and run, and live…) As you no doubt know, at least half of all women over 35 suffer from some form of incontinence, due to our physical biology. That doesn’t mean that men don’t too, and of course medical transition can make that much more likely, though it seems to be a more significant issue for women who transition (what you would call trans men). Public toilets are therefore more important for women than for men. It turns out that legally, it is both right and required to provide toilets (and bathrooms, but then public bathrooms don’t really exist any more) on the basis of sex. This is due both to physical needs and also for the privacy, dignity and safety of women, from men who just take limited resources because they can, or I’m afraid because they are one of the significant minority who get off on doing things that women don’t consent to, who literally find it exciting to force a woman to be in their presence while urinating or in any way vulnerable. Thee is NO response from women that that particular group don’t find sexually exciting. And it is important that convention and laws keep them out of the small spaces that are designated for women.
I can’t stop you using a women’s toilet, because you make your own rules and there are no checks or police on them. And I can’t stop you therefore making it more likely that other men will coat tail into doing it too. But that doesn’t make it legal. Thank goodness.
By the way, I have no issue with you shopping in Boots. No 7 is a great range.
