Ok, you have two points there.
Why would it be inappropriate? Because of gender identity issues or because of biological sex? I think if you try to formulate an explanation for me instead of simply asserting its inappropriateness you will need to use ideas about human sexuality and not just physical biology. A reasoning for this segregation, in my opinion, rests solely on antiquated gender theory which equates physical sexuality and gender identitiy. I don't think we should have a segregation at all, I think that there should be private washrooms, period. Please don't believe that I am suggesting we segregate on the notions of gender identity. century.
oh no way, sorry, no way would i or any other girl want guys sharing our bathrooms. its just not right. no point pretending that guys dont want it either i bet. tere ar certain things that are just private, and using a bathroom is one of them. besides, hard to talk about the guys if theyre in there with us
look at it another way. if you had a young daughter, would you let her run around naked in front of the male neighbours? so, if you wouldnt do that, why would you le her in a public bathroom
