It is now a century since Jewish-free zones first spread to the San Francisco Bay Area (“No Dogs. No Jews”). Nevertheless, this move seems frightening and unexpected, like a bang on the door in the night.

Berkeley law students are not the first to exclude Zionists. At the State University of New York at New Paltz, activists drove two sexual assault victims out of a survivor group for being Zionists. At the University of Southern California, they drove Jewish student government vice president Rose Ritch out of office, threatening to “impeach [her] Zionist ass.” At Tufts, they tried to oust student judiciary committee member Max Price from the student government judiciary committee because of his support for Israel.
