Brian Amerige, an engineer in product usability at Facebook, has quit the company, citing moral objection to its persistent, institutional bias against conservative viewpoints. Wrote Amerige in a recent leaked internal memo: “I care too deeply about our role in supporting free expression and intellectual diversity to even whole-heartedly attempt the product stuff anymore, and that’s how I know it’s time to go.”

The employee wrote another memo earlier in the year which described Facebook as an “intolerant” “political monoculture,” writing that “we claim to welcome all perspectives, but are quick to attack – often in mobs – anyone who presents a view that appears to be in opposition to left-leaning ideology.” This drew comparisons to the equally controversial memo by Google employee James Damore, who was fired for writing a detailed and well-researched criticism of his company’s internal intolerance and culture of unquestioning acceptance of leftist socio-biological narratives.

Amerige was previously at the center of a Facebook group called “FB’ers for Political Diversity,” composed of some of the few conservative employees who were concerned with their company’s unambiguous leftist bias.

In 2016, a bombshell report from anonymous employees at Facebook involved with the site’s curation of news and trending topics revealed that they “routinely suppressed” conservative news topics, conservative sites, and news about Facebook, while artificially injecting or elevating other topics and sites, such as #BlackLivesMatter, the New York Times, and the BBC. The whistleblowers pointed out that those in charge of curating the news at Facebook were overwhelmingly liberal, with very similar socio-economic and educational backgrounds, and often part of the journalist class themselves. Even mainstream conservative sites like National Review recognized the danger of Facebook’s ability to simply exclude right-wing voices, and that “for the moment, no meaningful market-based correction is possible.”

Facebook was also part of a swathe of social media and tech companies, including Apple, Google, and Spotify, which coordinated about two months ago to de-person free speech advocate, conservative commentator, and patriot Alex Jones. The site also landed in hot water when it conducted a survey asking its audience if men should be allowed to ask children for pornographic content, fitting a larger pattern of a correlation between far-left bias and a disturbing acceptance of pedophilia.

With the recent leak of an internal Google memo “The Good Censor,” embracing Orwellian censorship, rejection of free speech, and thought control, the time is running out for the political right to stand up to social media and tech giants such as Facebook. Amerige’s conscientious departure is the latest in a frightening trend which, if not reversed immediately, threatens to have the result of right-wing voices and their supporters being excluded from the online public space and forum of ideas entirely.

A Facebook spokesperson commented on Amerige’s departure, saying: “We wish Brian all the best.”
