The list was compiled by the LA-based Simon Wiesenthal Center.
"Never before, in recent memory, has the Simon Wiesenthal Center seen such a proliferation of anti-Semitism going mainstream," said the center's founder, Rabbi Marvin Hier.

The center cited two quotes from Thomas:
"Jews should get the hell out of Palestine. They should go home to Poland, Germany, America and everywhere else," Thomas said back in May.
"Congress, the White House, Hollywood and Wall Street are owned by Zionists. They put their money where their mouth is," Thomas said in December.
Director Oliver Stone came in at No. 2, with, "Hitler is an easy scapegoat throughout history and it's been used cheaply. He's the product of a series of actions. It's cause and effect."
The full list has been posted on the center's website.
According to its website, the center is "an international Jewish human rights organization that confronts anti-Semitism, hate and terrorism, promotes human rights and dignity, stands with Israel, defends the safety of Jews worldwide, and teaches the lessons of the Holocaust for future generations."
