A lecture about black holes was shouted down by pro-Hamas protesters because the lecturer is Jewish.
Tell me again how this anti-Israel movement isn't contaminated by, and festering with genuine racist hatred toward Jews.
Yes, by all means, be critical of Israeli policy without being anti-semitic; but, again -- clean your own fucking house. Call for these protesters to be disciplined like any other racist heckler on a college campus would be.
Condemn the behavior.
Don't ignore it. Don't try to bury it. Don't try to downplay it. Stop pretending that it's just a tiny minority of the anti-Israel people.
