The Gay & Lesbian Alliance Against Defamation (GLAAD) on Friday rejected Vince Vaughn's defense of a gay joke in the upcoming Ron Howard-directed comedy film The Dilemma.

Laughing about our differences brings us together, Vaughn said in responding to calls to cut the joke from the film, set for release in January.

After CNN host Anderson Cooper criticized the film's trailer during an appearance on The Ellen DeGeneres Show, Universal Pictures 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.”

In a blog posting Friday, GLAAD disagreed.

“We don't doubt Vince Vaughn's sincerity when he says he cares about people who are bullied for their 'differences.' Nor do we doubt that Universal executives feel the same way.”

“But this isn't about intent. It's about the fact that no matter what the intent, when 'gay' is used as a pejorative, it sends a message, particularly to youth, that gay taunts are acceptable. And it sends a message to LGBT youth that they are people who should be made fun of.”

“Vince is right. Comedy does bring us together, unless one of us is the punchline. Then it pushes us apart,” the group added.
