It's funny how radical academics think that they have the freedom to deny other academics their freedom. This is the exact case with the calls for an academic boycott of Israel. Professors do not have the right to try and deny their colleagues academic freedom via a boycott - that's called Stalinism. If extreme left-wing academics like Neve Gordon or Nitza Berkovitch insist that they have the right to deny academic freedom to their colleagues, I'm in favor of supporting them by immediately firing them and sending them abroad to work at any other university in the world. North Korea would appear to suit their ideologies.
