The passion that ousted the heads of the University of Missouri after protests over racial discrimination on campus is spreading to other colleges across the country, turning traditional fall semesters into a period of intense focus on racial misunderstanding and whether activism stifles free speech.

Hundreds of students demonstrated at Ithaca College in upstate New York on Wednesday, demanding the resignation of the college president, Tom Rochon, for what they said was his lackluster response to complaints of racial insensitivity on campus, including an episode in which two white male alumni on a panel called a black alumna a “savage,” after she said she had a “savage hunger” to succeed.

At Smith College, in Northampton, Mass., about 100 students demonstrated in solidarity with their counterparts in Ithaca and Missouri, while at the University of Kansas, the administration called a town hall meeting to give students and faculty a chance “to be heard” before any concerns about race on campus could grow.

At Claremont McKenna College in California, the junior class president resigned Tuesday after a furor over a Facebook photograph that showed her posing with two women who were wearing sombreros, ponchos and mustaches for Halloween. A campus demonstration followed on Wednesday.
