Former New York City Mayor Rudy Giuliani and former New York Governor George Pataki are among the big names expected to join the rally tonight protesting the Metropolitan Opera's premiere of "The Death of Klinghoffer."

Some are saying the controversial opera  - which is based on the 1985 murder of American Jew Leon Klinghoffer on a hijacked cruise ship - glorifies Palestinian terrorism, since the story is told sympathetically through the perspective of the killers.

On Outnumbered, Jedediah Bila defended the Met's right to stage this opera and said good art is supposed to be controversial.

"People are free to protest, but the Met is also free to put something on. And if you don't like it, guess what? You don't have to see it," Bila said.

Kimberly Guilfoyle, however, thinks that the opera is in very poor taste.

"I don't understand the point here," Guilfoyle said. "I'm glad people are protesting ... I'm happy for the people that don't go and see it. I hope it closes soon."

"It's glorifying terrorism."
