Actually, it has been stated you can make transgender characters in the game, so I just LOL at the thought of her fuming over finding out about this.
Whatever, she's a hack even beyond that these days. Why the fuck she thought it was smart to say wizards peed/pooped wherever and just used magic to clean it up back in the day is A) insanely stupid and B) completely contradicts a significant plot point in Chamber of Secrets regarding a bathroom and when it was built. Dumbass can't even remember her own continuity before spouting out bullshit.
