Why was the city of Los Angeles so scared of modern art in the mid-20th century?

In 1939, conservatives on the county museum board turned down a gift of modern works from the collection of Walter and Louise Arensberg. In 1944, the Arensbergs tried to interest UCLA in the collection, but nothing came of their offer. Vincent Price, Edward G. Robinson, and Fanny Brice founded the Modern Institute of Art to keep the Arensberg collection in Los Angeles, but the institute closed when funding ran out. When James Byrnes, the first curator of modern art at the county museum, sought to buy works by Jackson Pollock and Mark Rothko in 1947, he was advised by one of the trustees to keep the paintings off the museum walls. More
