With Muslims worldwide outraged by a short video posted on YouTube, Fox News Radio commentator Todd Starnes posed the question: Why isn’t “South Park” under federal investigation for being anti-Christian?

"We have seen the administration come out and say, 'We condemn anyone who denigrates religious faith.' And they come out in regards to this anti-Muslim film," says Starnes while at a panel discussion. "Well, that's well and good, but my question is: When has the administration condemned the anti-Christian films that are coming out of Hollywood? Where are the federal investigations into shows like 'South Park,' which has denigrated all faiths? Where is the outrage when people of the Christian faith are subjected to this humiliation that is coming out of Hollywood?"

For 15 years, the crudely animated Comedy Central series “South Park” has taken on many controversial topics, including most major religions, as noted by Clicker. The show has seen Christianity spoofed with Jesus Christ living as a resident of South Park, priest sex scandals being mocked, and many other instances that some religious viewers could find offensive.

The show also features parodies of Judaism, with the character Kyle being made fun of by Cartman for his beliefs. Mormonism and Scientology both have come in for detailed segments about their beliefs, both portrayed as ridiculous.

There was even an episode featuring a depiction of Muhammad as part of a superhero group consisting of Jesus, Moses, Joseph Smith, Buddha, Krishna, Lao Tze and an Aquaman-type character named Sea Man. The episode titled “Super Best Friends” aired in July 2001, two months before the Sept. 11 attacks.

Sensititivy toward religious feelings is again a hot topic thanks to the anti-Islam film “Innocence of Muslims,” which has set off violent protests in many countries. Though Starnes implies that there has been a federal investigation of the film, there are no reports to back up that statement.

A Californian with ties to the film was questioned by police, but not because of the film itself, which is protected under the First Amendment. Bloomberg reports that Nakoula Basseley Nakoula, a convicted swindler, was of interest to law enforcement officials for possible parole violations.
