The fliers depicting men in camouflage, wielding guns and an American flag, appeared in men’s restrooms throughout Texas State University: “Now that our man Trump is elected,” they said. “Time to organize tar and feather vigilante squads and go arrest and torture those deviant university leaders spouting off that diversity garbage.”

A year after students at campuses nationwide pushed for greater sensitivity toward cultural differences, the distribution of the Texas State fliers was just one of several episodes this week suggesting that the surprise election of Donald J. Trump is provoking a round of backlash on campuses.

At the same time, universities are trying to address more generalized fears about the country’s future, organizing campus meetings and counseling sessions and sending messages to students urging calm.

“A lot of Muslim students are scared,” said Abdalla Husain, 21, a linguistics major at the University of Tennessee, Knoxville, who is of Palestinian ancestry. He said some Muslim students on campus were afraid to go outside. “They’re scared that Trump has empowered people who have hate and would be hostile to them.”
