It started with a course boycott and ended with a Nazi cartoon.
In the spring of 2014, a series of ugly incidents rocked the campus of Vassar College, a small liberal arts college just north of New York City.
It started with a boycott protest against a course that involved travel to Israel and the West Bank, including forcing a professor and students to walk a gauntlet of people ululating (audio example here). It culminated in the posting on social media of a Nazi cartoon portraying Jewish control of the U.S.
The group mounting the protest and posting the plainly anti-Semitic cartoon was Vassar Students for Justice in Palestine.
