A Chicago high school displayed an American flag like a doormat by unfurling it across the floor as a part of an art project to address to “complexities” of free speech.

The principal of York Community HS said the display is a recreation of a 1989 art exhibit and is in “no way meant to disrespect the flag,” according to the Chicago Tribune.

“It was used for students to reconcile their feelings about current issues and whether their First Amendment rights are protected,” the principal, Erin DeLuga said in the letter posted online.

“These are difficult conversations when challenging students to think critically about issues that are relevant to them, school, and society.”

The school’s Facebook page was flooded with negative comments.

“Absolutely disgusting! Teach the kids respect, not your political agenda. The American Flag should never be on the ground,” Rob Angelo wrote on the page.

The original exhibit by artist Dread Scott was displayed at the School of the Art Institute of Chicago. Back then, it was called “disgraceful” by President George H.W. Bush, the Tribune said.
