Dartmouth College has called off classes  for today to discuss the college's "commitment to fostering debate that promotes respect for individuals, civil and engaged discourse, and the value of diverse opinions." A series of programs, featuring faculty members and a diversity and social justice consultant, will be held. The college's decision follows a series of threats received by students online -- some citing the students' sexual orientation or race, college officials told the Associated Press.  The threats followed a protest in which some students interrupted a program for high school students who have been admitted to Dartmouth. The protesters chanted "Dartmouth has a problem," and said that the college wasn't doing enough to prevent homophobia, racism and sexual assault on campus. The online threats were subsequently posted -- some against students who had participated in that protest, and some against other students.
