Protesters gathered Wednesday outside the home of a former Sigma Alpha Epsilon member who was expelled from the University of Oklahoma for his role in a racist chant that was captured on video.

“Racism is taught,” the crowd yelled outside the Dallas home of Parker Rice, the Dallas Morning News reported. “Silence is consent.”

According to the newspaper, the group also shouted: “Teach your kids another way. No modern-day KKK.”

The video — which sparked outrage online and was rebuked both on a national level and across the OU campus — shows Rice and some of his SAE brothers using a racial slur in a loud chant on a bus.

Rice apologized for the chant on Tuesday night, saying in an statement through his father that he was “deeply sorry” for participating.

A second student, Levi Pettit, was also identified and expelled earlier this week.

In his apology, Rice noted that his family was “not able to be in our home because of threatening calls as well as frightening talk on social media.” Nobody was in the home at the time of the demonstration, according to reports.

The protest was arranged by the organization Next Generation Action Network, the Morning News reported. The NBC affiliate in Dallas said “about two dozen” people participated; the Associated Press said it was “about 20” people.

“This was brought to us very boldly, and we need to address this issue very boldly,” Next Generation Action Network founder and president Dominique Alexander told the Morning News. “We are coming here so the neighbors, everybody knows what is going on.”
