A black man carrying an American flag confronted protesters outside a federal courthouse in Portland on Sunday, telling the mostly white crowd that “none of you guys represent black lives.”

The unidentified man can be seen in video footage attempting to stop the protesters from breaking through a gate and “occupying” the steps of the graffiti-covered courthouse.

“If you came here for justice, come here and stand with me,” the man says. “I’m here for justice. I’m not here to tear down this f–king fence. I’m not here to spray-paint.”

He adds: “If you don’t wanna get gassed: Stop!”

When a member of the group tries to tell the man they have a right to peacefully assemble, he replies, “This ain’t peaceful.”
