Racist, white nationalist propaganda was found posted at four separate locations on the main campus of the University of Maryland on Monday. Two of the hate-inspired flyers were put up at an academic building, with one appealing to "all white Americans" and the "white nation" to report undocumented immigrants to law enforcement authorities.

Each flyer carried the essentially same messages but were worded differently from one another, the Washington Post reported.

"It is your civic duty to report any and all illegal aliens. They are criminals. America is a white nation," one of the read.

"Carry the torch of your people," the other said.

It was the third such instance on campus in the last three months.

Similar messages have been popping up on college campuses across the country in recent months, including in February when anti-Islam signs were posted at the University of Texas at Austin, the Houston Chronicle reported.

"Imagine a Muslim-free America," one sign said over the images of the World Trade Center, an apparent reference to the terrorism on Sept. 11, 2001 that targeted New York City in part.

Immigration rhetoric stemming from Trump's proposed travel ban has increased recently, primarily placing Hispanics and Middle Eastern immigrants under the spotlight as the two groups seemed to be lopsidedly targeted by the Immigration and Customs Enforcement (ICE) federal agency for deportation. The ongoing spate of ICE raids across the country has likely emboldened the type of actions on campus that were seen Monday in Maryland.

Most college students encourage free speech except when that speech is hateful, according to a Gallup poll published last year.

A college in Pennsylvania was working to confront racism on its campus after a blackface incident took place last month — Black History Month. Millersville University students, staff and administrators held and open forum last week to air grievances, prompting the school's president to apologize for what many criticized as a response that was not firm enough, local news outlet Lancaster Online reported.

"I feel like I’ve failed you, and I take that seriously. I’m here to look for how we can change the culture," Millersville President John Anderson said. "We’ve got to step it up, and we will. I pledge that to you. Let’s have that dialogue."
