HILLSBORO, Mo. – A dispute over a transgender student’s access to school restroom and locker facilities boiled over this week as hundreds of students walked out to protest her special treatment.

Lila Perry, a boy who wants to be a girl, told her teachers and administrators at Hillsboro High School that she’s no longer content using a unisex faculty bathroom for her senior year, and wants officials to grant her access to girl’s restrooms and locker rooms, the St. Louis Post-Dispatch reports.

Concerned parents and taxpayers packed a school board meeting last Thursday to voice their opposition to Perry’s requests, with most citing the privacy rights of school’s sexually normal female students.

“The girls have rights, and they shouldn’t have to share a bathroom with a boy,” parent Tammy Sorden told the news site.

Like many other Hillsboro parents, she doesn’t believe Perry’s gender identity should grant her special privileges “while the girls just have to suck it up.”

So many students wanted to protest Perry’s restroom request that school officials made special accommodations for excused absences through second- and third-hour classes Monday, before asking students to return to class after about two hours.

In total, about 150 students walk out in opposition, while about 30 to 40 did the same in support of Perry, who has reportedly identified as a female since age 13, KMOV reports.

Perry has since dropped out of her physical education class over the ordeal, but continues to use the girl’s bathroom at the school.

“I wasn’t hurting anyone and I didn’t want to feel segregated out. I didn’t want to be in the general neutral bathroom. I am a girl, I shouldn’t be pushed off to another bathroom,” Perry told the news site.

“There’s a lot of ignorance, they are claiming that they’re uncomfortable,” she said of her female classmates. “I don’t believe for a second that they are. I think this is pure and simple bigotry.”

Student Sophie Beel she’s uncomfortable with the situation, and doesn’t consider Perry truly transgender.

“I find it offensive because Lila has not went through any procedure to become female, putting on a dress and putting on a wig is not transgender to me,” she told Fox 2.

Parents and other relatives of girls attending Hillsboro have also protested against Perry’s use of female school facilities, carrying signs along Old Highway 21 that read “Girl’s Rights Matter.”

“Boys need to have their own locker room. Girls need to have their own locker room and if somebody has mixed feelings where they are, they need to have their own too,” adult protester Jeff Childs told KMOV.

“I’m not comfortable with it,” Britney Heimos, a 2008 Hillsboro graduate who was at the school to pick up her brother, told the Post-Dispatch. “There is nothing wrong with being different. But when you are different, there are sacrifices.”

Kelli Hopkins, spokeswoman for the Missouri School Boards’ Association, said the federal government requires schools to tolerate transgendered students, and to allow them to use whatever facilities they choose. Restricting their access in any way could result in a loss of federal funding, she said.

“The Office of Civil Rights has issued an opinion that says, if you do this, you have engaged in gender discrimination,” Hopkins told the Post-Dispatch. “At the same time, there is no case law or statute in Missouri that says this is against the law.”

The complicated situation is one Hopkins said she’s had to explain to an increasing number of school administrators in recent years as more students identify as transgender.

“I got no calls on this five years ago,” Hopkins said. “I’ve gotten at least half a dozen recently.”
