It's a problem because there are perverts in sheep's clothing that hide under identity/gender and will go to other bathrooms as an excuse to perv on the opposite gender.

Would you feel comfortable if you were a woman and some creep of a guy with feminine-like features but still ultimately a guy, came in to the women's bathroom just to try and sneak peek for nudes?

I mean, if someone does that, it says a lot about someone. So not only are they a perv, but are they also into the idea of someone shitting and pissing? Technically I say you are, if you do this.

I kinda get wanting a restricted space for privacy, but unisex bathrooms with multiple stalls exist. The key is making them peek proof and reasonably secure. Once that's out of the way, the difference between a line inside the bathroom and one outside it becomes moot. At that point, it really isn't about having privacy any more since a public restroom is inherently impossible to make fully privacy centric what with sound proofing being cost prohibitive.

If anything, it would be better to have the same space set up unisex (or unigender if you prefer) since it would cost less to make the now bigger bathroom, and improve some of the waiting times for a place to excrete. Well, with the flaw that you would lose the availability of urinals in the real world, so that would end up being a major drawback for space and use management. Point still remains that public restrooms don't have to be segregated to be safe and useful.

I just want to say it’s not my business where you do your business. That is all.

Why is even pronouns needed for toilet separation? Should be as easy as "this toilet is for people who wants to pee standing up", "this is for people who want to pee sitting down", and "people who want to pee in a cup can go to Berghain"

I never understood this.

We're all here to piss and shit and wash our god damn hands. I don't care how you do it.
