YouTube have placed some of the videos of the conservative PragerU channel on “restricted mode,” designed to stop children from viewing inappropriate adult content.

The channel, PragerU, which is short for Prager University, produces short, concise, graphics-based videos for young people which are broadly based on Judeo-Christian values and conservatism, but features videos from the likes of feminist academic Christina Hoff Summers, human rights activist Ayaan Hirsi Ali, and Taleeb Starkes, author of Black Lies Matter.

YouTube has marked some of the channel’s videos on topics such as whether George Bush lied about the Iraq War, the university “diversity scam,” and whether Sharia Law and freedom can coexist, as part of a restricted mode.

According to YouTube, restricted mode is designed “to help screen out potentially objectionable content that you may prefer not to see or don’t want others in your family to see.”

On the channel’s Facebook page, PragerU says that they have “worked quietly behind the scenes for months to resolve this, but YouTube’s censorship continues, leaving us with no option but to go public,” before asking users to sign a petition demanding that YouTube stop blocking the videos.

“There is no excuse for Google and YouTube censoring and restricting any PragerU videos, which are produced with the sole intent of educating people of all ages about America’s founding values,” the group states on its website.

The non-profit adds that YouTube “defended their restrictions of the videos,” although does not list their justification apart from the fact the company “takes into consideration what the intent of the video is.”
