There is parental backlash in Clarkstown after a slideshow presentation on the Black Lives Matter movement at a middle school was rescheduled without warning.

It was created by eighth graders at Felix Festa Middle School to inform students about the Black Lives Matter movement.

Dan Brownstein is a parent of rising fifth grader set to attend the school. He says he's disappointed that the event was canceled after portions of it were posted on a Facebook group.

Some parents say the presentation isn't appropriate for students.

"The anger and the racist comments that were coming out of people were shocking that I live in a community that feels this way," says Brownstein.

The school district tells News 12 that the event isn't canceled, instead they are rescheduling it "in order to allow for additional preparation so that the material can be shared in the most productive and effective manner."

"I didn't see anything offensive or indoctrinating anyone to anything other than reality," says Wilbur Aldridge, regional director of the NAACP.

Aldridge says its important students learn about social justice issues like this.

"It's a conversation that needs to be had by adults as well as children," he says.

The slideshow is part of a school initiative called "No Place For Hate."

The district boasted about it this week on Twitter after a state regent visited the school and found the initiative "inspiring."

Although the district says it's rescheduling the slideshow presentation, it has not given a date.
