Neighbors are losing their tolerance for the Museum of Tolerance, which features exhibits dealing with the Holocaust, racism, extremism and human rights abuses around the world. People who live near the museum in West Los Angeles are opposing plans to build a two-story cultural center that could be rented out for private events such as weddings. The museum also wants to expand operating hours to midnight when such events are held, and to reduce its 30 1/2-meter buffer zone from homes 6 meters. But some neighbors have collected about 70 signatures on a petition calling on the city to reject the proposal. "They don't care about us as neighbors," said Sharron Lerman, who lives two blocks away and is a museum member. "Very insensitive."
