I don't understand the "(optional!)"bit you've added here. Could you explain?
That no one is obliged to use them of course.
There's no 'of course' about it. I thought you were suggesting it would be optional for venues to include them. Of course there is no practical way for most venues to accommodate all of these different toilets. Which is why single-sex facilities, or unisex but fully contained and lockable with sink etc. in the cubicle, plus accessible toilet, is the only realistic proposal.
for female-assigned , “gender critical” feminists, who are particularly worried about being raped by trans women
I mean, because this really does come across very much as you mocking the fact that women and girls have a reason to fear males in their toilets, changing rooms, hospital wards, prison cells, etc.
There's nothing funny about it. What a sick place to try to use 'humour' - by ridiculing women who are scared of being raped. Fucking disgusting.
Males are a risk to females. That's why we have single-sex spaces. I don't care how they identify.
The rest of it is just bollocks, deliberately distorting reality and trying to say "look over here instead!" every time anyone points out the most basic facts - like the fact that 'male' isn't a word that is difficult or complex to define.
I get that trans-identifying males are determined not to let us be safe, or have privacy, or have dignity, or have a space of our own with no men in it. I get that. It's no surprise - men get really fucking angry at women saying no to anything. I really have to go now before I waste my entire afternoon doing this.
