At the time Dr. Kermit Gosnell was caught, prosecuted, and convicted for removing live children from women and then killing them, the line went out that Gosnell's moral confusion was an outlier, that the pro-choice side stood as one with the pro-life side in condemning Gosnell and that there would be nobody trying to whitewash or minimize Gosnell's crimes.
Kickstarter has demonstrated that this was aspirational at best and that the pro-choice side has a problem. Slate's not exactly a right wing news source but they see the problem of a discriminatory review process just fine. For those who are unfamiliar with Kickstarter, a successful fundraising project might have dozens of short videos talking about details of the project. Kickstarter pretty clearly laid down the line that talking details about Kermit Gosnell could get the entire project pulled, or at least pulled from the internal search engine. In a time limited process like Kickstarter, getting pulled from the search engine can mean the difference between getting funded and getting nothing. The filmmakers were right to seek a different platform where they would not have to pull their punches in their crucial communications during the fundraising campaign out of fear that a reviewer with the same sort of moral confusion that led to Gosnell's life sentence would pull their project.
Update: The film was successfully funded via Indiegogo
