@viann_lena nodds in agreementOne major problem is that the venue is designed with cisbinary gender segregation at sanitary infrastructure in mind and #Germany still mandates that per building code to this day.Obviously the ideal solution to it would be to just designate said rooms based on their installed capacity and amendities:How many toilets/pissoirs/stalls/sinks/diaper changing cabins are there?How many of these are wheelchair-accessible? (If none are, where are the closest ones and how to get there accessibly!)Maybe add like some door lock-based contact switch that shows if all stalls are occupied or vacant (like have a light at the front door or something.) So people ain't standing in lines or inside the hallway.Still, #39C3 should not feed into TERFy narratives by even dabbling with cisbinary gender segregation to begin with.What would improve safety would be silent buttons to press for help regardless if it's due to some personal/private issues (cuz that does happen and it's a statistical inevitability!) or creeps (when it comes to safety!).I mean, what do people want to use the restroom? To relive themselves of "dark matter" in all it's states and/or deal woth whatever other personal hygiene matters they have to on a short notice. People ain't gonna hang out in there (hopefully!) and the most pressing concern with any toilet (beyond cisbinary segregation being bs!) is how sanitary it is and whom to call in case it isn't anymore - regardless of who's fault it is.The "Equal but Seperate" criticism is understandable and whilst the organizers can't sledgehammer and reinstall different sanitary setups, they shure as hell could just tell people to "use whatever sanitary infrastructure fits your needs" and "don't be an asshole"... Cuz I certainly don't care whoever else is doin' whatever else in the neighbouring stall or pissoir as long as they don't make it a problem for me by unsolicited and nonconsensual share of bodily excretions onto me or my belongings!In any toilet, I just want to take a piss, dispose of dark matter, remove any residue of the latter, wash my hands and GTFO cuz any event is too expensive and precious to waste time sitting on the loo. And the faster I get out the sooner someone else can also relieve themselves!
