Okay, this one literally made me LOL. For a good while too. According to the St. Louis Post-Dispatch:

“In the middle of last school year, Lila Perry came out as transgender. Before that, she had been living as a gay male.”

I know, I could hear your proverbial double-take through my monitor. Don't worry, you didn’t skip over anything. Understanding that, yes, Lila Perry is a boy—and the writer is using female pronouns to refer to him—will unlock the secret of the riddle. Pretty much every news source covering this story refers to Lila in the same way. Because, tolerance.

On with the story. After Lila Perry decided that he was a she (or maybe even a ze, the new term being used), figured it was time to stop using the unisex bathroom. There's that double-take again. To answer your question, yes, there already was a unisex bathroom designed to accommodate such a situation. See, compromises aren’t enough—he wanted to be who she really was… Or something like that. He said:

“I wasn’t hurting anyone. I didn’t want to be in something gender-neutral. I am a girl. I am not going to be pushed away to another bathroom.”

See that's the problem. The only leftist barometer as to whether something is allowable is whether you are physically harming another individual in that specific moment. Unless of course you're a dude with a wig, then even having your feelings hurt is cause for national alarm.

Unfortunately for 'Lila', most girls weren’t into thinking that he was a she. Most girls, actually did feel not only uncomfortable, but physically threatened by what was clearly a boy, using their restroom.

“The girls have rights, and they shouldn’t have to share a bathroom with a boy,” said Tammy Sorden, who has a son at Hillsboro High. "It is fine to be different," she said. "But it is not right to give Lila special treatment while the girls just have to suck it up.”

Reasonably enough (or intolerantly enough, depending on how you look at it) students and parents began a peaceful protest.

Lila and her liberal supporters then proceeded to comparing the entire situation to the time when black people weren’t allowed to share a bathroom with white people. Hm. Reducing an entire race of people (with a rich a varied cultural history), to one's personal preference of sexual friction... yeah that's appropriate. Because, tolerance.
