The crowd-funding site Kickstarter is being accused of censoring a group of filmmakers who are planning a movie about the abortion house of horrors controlled by convicted murder Kermit Gosnell.

The filmmakers say that Kickstarter told them describing the acts committed by Gosnell in the movie’s description were a violation of the site’s terms of service.

“We ask that the phrase ‘1000s of babies stabbed to death’ and similar language be modified or removed from the project,” wrote a Kickstarter representative in one of their communications with the group.

Phelim McAleer, one of the producers of the film, said that while Kickstarter objected to their references to abortion, the site allowed 16 projects that involve stabbings, 5 projects about incest, 44 about rape and 28 that have the F-word in the title.

Kickstarter told the National Review on Friday that they had approved the project as submitted despite the e-mails shown by the filmmakers that show they were told to censor their wording.
