Tony Perkins, president of the Christian conservative Family Research Council (FRC), has criticized the Smithsonian's effort to document the history of sexual orientation.

The Smithsonian's National Museum of American History announced last month a significant expansion to its LGBT history collection.

Artifacts being added to the collection include studio props from the hit television series Will and Grace and diplomatic passports from the nation's first openly gay ambassador and his husband, David Huebner and Duane McWaine, respectively.

Perkins criticized the museum for “ignoring the destructive side effects of homosexuality” and attacked the collection as “propaganda.”

“Is it the Museum of Natural History or 'Unnatural History'?” Perkins told his radio listeners. “You can't blame people for asking after the Smithsonian's decision to add a special exhibit on the LGBT movement. The collection highlights everything from Will & Grace show props to a transgender pride flag. Sports, politics, and cultural memorabilia are all part of the propaganda, which – like most Smithsonian projects – [are] funded by taxpayer dollars.”

“This is just another platform for the Left to rewrite history – and ignore the destructive side effects of homosexuality. Students are already bombarded with the LGBT agenda, do they really need to walk past exhibits treating its extremists as heroes? The Smithsonian may know art, but it should stop trying to frame the culture debate.”
