An anti-Israel hate mob took over San Francisco State University last week while the Mayor of Jerusalem was speaking. Using megaphones, they were so loud and vicious that the event had to be canceled. Police reportedly stood by and did nothing to silence the bigots.

Troubling behavior like this is not uncommon on college campuses around the world. Those of us who find it outrageous—and everyone should!—can make our voices heard by signing a petition created by The Israel Project. When the petition reaches 20,000 signatures, TIP will present a copy to California Governor Jerry Brown.

Let’s do our part to encourage free speech and discourage discrimination in every public place.
