So if someone presenting as female pops in, uses the cubicle and basin hygienically and pops out without causing a ripple, we don't have a problem, do we? It's probably been happening forever
it's in this area where the TRA have probably caused the most damage and shown it's not actually about Trans rights but about controlling women and getting access to their spaces.
In the past I personally never had an issue with trans women/ transexuals using the ladies.
But the TRAs couldn't accept that other women might not be comfortable and demanded access at all costs.
They gave legitimacy to people like Yaniv to enter women's spaces and they have made people like me who were previously reasonably open to transwomen using women only spaces (as long as they weren't causing any harm) determined to keep women's spaces single sex due to the risks of predatory men abusing self ID.
Seems a bit of an own goal if the end goal truly was greater tolerance of trans people in society (I suspect it wasn't).
