Michael Lerner, a rabbi and the editor of the leftist Jewish magazine Tikkun, has been the target of vandalism because of his magazine’s support of Richard Goldstone, the South African judge who led a committee that published a report in 2009 concluding that Israel had taken actions amounting to war crimes, Rabbi Lerner said on Wednesday.

Rabbi Lerner, who lives in Berkeley, Calif., said the third incident of vandalism in less than a year occurred at his home on Tuesday night. Several posters depicting him as a Nazi were glued to his front gate and his garage door and discovered Wednesday morning. On Monday night, the magazine held its 25th anniversary celebration, at which it honored Judge Goldstone, who was also named in the posters.

The first incident of vandalism was in May 2010, when Rabbi Lerner’s home was vandalized with black spray paint and posters. Another incident came about a month later, he said.

“As much as I’ve been used to having all kinds of hate stuff put out about me, this is the first time they’ve actually come to my home,” Rabbi Lerner said. “I want people to know that when you’re taking this kind of a stance in the Jewish world, that it can be very scary. We’re up against some real, live hate.”

He said he had “no idea” who was behind the attacks.

Sgt. Mary Kusmiss of the Berkeley Police Department said that there were no suspects and that the police were investigating.

Because of the nature of the vandalism, it is being investigated as a hate crime, she said.
