OMAHA, Neb. – A Omaha Public Schools meeting focused on proposed changes to the district’s sex education curriculum ended with parents shouting at and shoving each other to make their point.

District officials were considering adding instruction on topic of emergency contraception, abortion and gender identity at a meeting Tuesday that drew more than 1,000 people to the auditorium at the district’s headquarters, where opponents seemingly outnumbered supporters, according to Jay Irwin, a University of Nebraska professor who detailed his experience on Facebook.

“The room was charged from the beginning. Anti-CSE (comprehensive sex education) folks had big red stickers to show their opinion on the topic at hand. The pro-CSE folks I was sitting with felt definitely outnumbered,” Irwin wrote. “There were also a number of young people, either high school students or folks who had just graduated high school in attendance, which I was happy to see.”

District officials gave an overview of the sex education curriculum, which is optional, as well the results of a parent survey that showed overwhelming support for comprehensive sex education, or education that goes beyond abstinence.

“The last topic area slide concerned people’s opinions about the need to cover sexual orientation and identity, as well as gender identity, in CSE. Well over 60% of parents agreed that these topics should be included according to the results,” Irwin wrote. “The room broke out into two different responses – first a very loud boo-ing group, seeming to indicate their disapproval of covering these topics. And a (felt like to me at least) smaller group of folks clapping in support of the need to include these topics.”

School officials apparently moved on with their presentation by explaining that data shows comprehensive education is more effective than abstinence-only programs – “it’s just a fact” school officials. OPS officials then passed out copies of guidelines for the curriculum, but hadn’t anticipated the large crowd and did not produce enough for everyone, according to Irwin.

Assistant superintendent Ranae Kehrberg “also announced that the plans for the evening had to shift – we were originally supposed to have small group discussions, but that was impossible with 1,000+ people, so all comments were requested on the physical documents themselves.

“This set folks over the edge. A woman started screaming something in the front about needing to protect her daughters … Other outbursts were happening around the room,” he wrote.

One attendee, Megan Hunt, posted a video to Facebook of the mother Irwin referenced screaming loudly: “I have five daughters. Five daughters. Who keeps them pure? Nobody! I am! Not OPS! Not OPS!” to a roaring applause.

The video went viral and launched the hashtag #puritymom, RawStory reports.

Irwin’s lengthy Facebook post went on to make clear he supports comprehensive sex education, and detailed alleged threats and violence leveled at sexually abnormal folks who attended.

“A group of young LGBTQ people were threatened with violence by a mother and her son for being there, for not apologizing for the sexuality, and for supporting education that was respectful of their identities,” Irwin wrote. “They were called evil, sinful, and told they were going to hell. The advisor that brought them, who is also queer identified, was told that she was teaching them how to be gay and that she should be ashamed of herself.”

“When the advisor asked that the person be respectful, that’s when the treats (sic) of violence began,” he wrote. “These are no doubt just scratching the surface of what happened tonight at the OPS TAC building. These are just two stories that I know about.”

Opponents of comprehensive sex education said the new curriculum would teach students sex positions, how to masturbate, could start as early as kindergarten, involved Planned Parenthood and would encourage teen sex.

“That’s disgusting,” parent Bernie Garcia, father of a fourth-grader, told Live Well Nebraska. “That’s not right. Children should learn about sex when they become adults.”

District officials distributed frequently asked questions sheets that said the curriculum would start in fourth grade, and not involve Planned Parenthood or the organization’s materials. The district would continue to encourage abstinence, and would not hand out birth control or coordinate abortions, district officials countered, according to the Associated Press.

“It’s really frustrating that we’re seeing propaganda being distributed this evening,” said Kasey Hesse, a volunteer with the Women’s Fund of Omaha, which help craft the curriculum.

Proponents said better sex education is needed to combat the county’s climbing chlamydia rates among youth. A meeting earlier in the year drew about 150 people, but social media campaigns from groups as diverse as Nebraskans for Founders’ Values – a Christian conservative organization- to Omaha Atheists encouraged their members to speak out against the changes, Live Well Nebraska reports.

“We want to make sure our kids aren’t being taught things we don’t believe in,” said William Jefferson Sr., father of an eighth-grader told the site. “We don’t believe in things like gender identity. Things like sexual orientation should be taught at home.”
