Laughing about our differences brings us together, Vince Vaughn said Thursday in responding to calls to cut a gay joke from the upcoming Ron Howard-directed film The Dilemma.

Last week, after CNN host Anderson Cooper criticized the film's trailer during an appearance on The Ellen DeGeneres Show, the studio responded by altering the online version of the trailer.

The new trailer no longer includes Vaughn's character in a boardroom saying, “Electric cars are gay. I mean not 'homosexual' gay, but 'my parents are chaperoning the dance' gay.”

Vaughn said that while he was “outraged” by bullying and persecution, joking about our differences “brings us together.”

“Drawing divided lines over what we can and cannot joke about does exact that; it divides us,” he said in a statement to celebrity website E! “Most importantly, where does it stop.”

The gay rights group GLAAD is spearheading an effort demanding Universal Pictures delete the joke from the final film, set for release in January.

“If Universal insists on keeping the homophobic material in the final movie they are helping to fuel a climate that endorses and promotes anti-gay attitudes,” GLAAD's online petition reads.

The group also wants studio executives to pull the plug on the film's theatrical trailer, which has not been altered.

“When 'gay' is used as a pejorative in such a public way for millions to see and laugh with, it legitimizes and propels the many taunts that gay people endure,” Jarrett Barrios, president of GLAAD, said in a statement. “Amidst a rash of bullying related suicides and anti-gay hate crimes, we need to tell Universal and America that our community is tired of being used as a punch line.”
