APEX, North Carolina (WTVD) -- Just a few camera phones were rolling video last Friday as the Apex Friendship High School Step Team performed at their very first schoolwide pep rally."It was fun, everyone wanted to perform. Everyone was looking forward to it," said a 16-year-old sophomore member of the step team who did not want to use her name for this story. She's one of the 10 students on the team, which is made up of all African-American students.The team's excitement about the performance turned to disgust when the team member saw the Snapchat post by one of her white classmates -- a photo of the team's performance with a caption referring to them as slaves.The Snap read, "Plantation owner watches his former slaves rejoice and celebrate their newfound freedom. Circa 1864.""I mean it's nothing new; it's happened before," the team member said. But she said this time the post, which was deleted less than a half hour later, was more public. "Honestly, we're mad, and we want to see more done than what's being done."Today we met with the assistant principal," she continued. "He apologized and he said he's going to handle it."In an alert sent out to Apex Friendship High School parents Monday, principal Matt Wight called it, "a highly offensive racial remark."He said administrators had investigated, identified the student, and the student was being disciplined under Wake County Public School policy. Wight said he spoke with the step team members to reassure them this type of behavior "would not be tolerated." He's pledged to work to address the issue in a "positive, constructive way to improve relations with all of our students."The step team member said she believes this incident and past racially-charged cases have gotten far too little attention from administrators."We're coming to them asking for help, and we're expecting them to do more," the team member said.The racist Snapchat post is the latest in a string of ugly racially-charged cases this school year across the school system.A group of community activists along with the Raleigh-Apex branch of the NAACP fought for a meeting with Wake Superintendent Jim Merrill to talk solutions.That meeting is scheduled for May 3.
