It seems to me they've pretty much shown their true colors

Anti-Semites at Columbia in the news again with the new University President promising to investigate charges that Columbia has become an incredibly hostile environment to Jews and Israelis. Individuals supporting the professors accused of this type of harassment staged a protest, ostensibly to demonstrate that the professors are innocent of all charges. They kind of gave themselves aware with their protest signs, though:

"On Tuesday, about 50 students, faculty members and community activists held a news conference at Columbia to defend the accused professors there and denounce the backers of 'Columbia Unbecoming,' which was produced by the David Project, a Boston-based group that seeks to combat anti-Israel bias on college campuses. Some held aloft signs reading, 'Down with the Zionist witch hunt on campus!'"
