That made no sense, and what does location have to do with it?
If it's offensive to call a girl a girl at a girls' school how does that make any sense?
You're putting words in my mouth I never talked about how much sense it made. All I'm saying is this is a trivial matter that doesn't affect you besides making you annoyed. Thus being pissy about this is frankly, immature. I see a lot of nonsense everyday and I can look the other way around unless it threatens/challenges me.
If you wanna talk about how much I agree with it, you never know when a girl is not a girl, but I wouldn't go as far as banning people from calling others their assumed gender.
