SAN RAMON, Calif. – A LGBTQ “Acceptance Week” at Windemere Ranch Middle School will proceed as planned despite numerous objections from parents about the controversial program.

Parents voiced their concerns about lessons and videos loaded with LGBTQ issues during the school’s April 11-15 “Acceptance Week” some view as an “extended promotion” of topics that aren’t age appropriate for middle-schoolers, Inside Bay Area reports.

Parents started a change.org petition to highlight their objections to the LGBTQ Acceptance Week at Windemere, and have generated 646 signatures of support over the last week. The petition calls on school officials to restrict the weeklong event to April 11, a national day of silence in support of LGBTQ people, or face the possibility of a student walkout.

The petitioners also demand that school officials dedicate an equal amount of time to other highly controversial subject that seemingly divide students and the community.

“Acceptance Week clearly involves public efforts that are focused on the LGBTQ community. Such public efforts are well beyond any activities for any other single group, and are believed to be discriminatory,” according to the petition.

“Inequalities in such efforts are evident when comparing the time, resources and intensity devoted to lessons, activities, and promotional fanfare dedicated to the acceptance of the Lesbian, Gay, Bi-sexual, and Transgender group while ignoring acceptance and promotion of values represented in other diverse groups within our community.”

The petitioners contend they’re not opposed to LGBTQ lessons in general, but a week-long focus on those issues poses problems for students and parents who oppose the lifestyle.

“We are highly concerned about the extended promotion of LGBTQ by the Acceptance Week curriculum, which appears to indoctrinate our children, undermine parental guidance and humiliate those with religious, cultural and personal convictions not in agreement or acceptance with the promotional campaign,” the petition reads.

“Again, we are not against LGBTQ, but demand respect and equality for all segments of our community …”

The petition threatens a walk-out if the school doesn’t restrict the LGBTQ activities to one day, instead of the entire week, and threatens further legal action if school officials mark students who walk out as unexcused absences.

“We agree that no child should be harassed or subjected to humiliation for his or her convictions,” the petition reads. “Ironically, the activities and week-long pressure planned for Acceptance Week will likely bring humiliation to students not in agreement with the LGBTQ lifestyle.”

ABC 7 reports Windemere Ranch officials agreed to meet with parents to discuss their concerns about the Acceptance Week, but aside from a few small changes to the planned curriculum they refused to comply with the petition’s demands.

San Ramon Valley School District spokeswoman Elizabeth Graswich said “as part of the conversation (with parents) the videos aren’t going to be shown in full anymore.”

“The principal has decided to take certain portions of them out and only show a portion of it.”

Graswich told Inside Bay Area the district “will be sending an email to all Windemere Ranch parents sharing that we had the meeting and that we will be moving forward with the week and lesson plans as stated in the email (originally sent to parents) on March 31.”

Graswich said district superintendent Mary Chelton reviewed the lessons and videos to be used during the Acceptance Week “and believes that they are focused on education, respect and acceptance.”

“This is a message peers wanted to get out to their peers to make sure all students feel comfortable on campus and that’s something that’s important to us,” she told ABC 7.

Several parents told the news site they believe the district is making a mistake.

Parent John Roca said the lessons are “not age appropriate at all.

“We felt it’s a subject better addressed by parents at home,” he said.

Other parents believe that the district’s “acceptance” and “respect” should extend beyond LGBTQ students.

“So we want to have four other groups, you know, teaching tolerance all around,” parent Robyn Barney said.
