After the election, the left began pressuring social media giant Facebook to crackdown on “fake” news.

Democrats believed Hillary Clinton lost because people ignored the liberal media and received their news from alternative sources.

Now Facebook has announced a plan to deal with “fake” news that has many conservatives worried the social media site is about to start suppressing their views.

Facebook founder Mark Zuckerberg recently announced the site had entered a partnership with third party fact-checkers that will apply warning labels to stories labeled 100% false.

But critics point out the organizations involved in the fact-checking are liberal partisans who are biased against conservatives.

For example, the organization PolitiFact has a long record of bias against conservatives.

One example is when Congressman Ron Paul said during a 2012 Republican Presidential debate that the federal income tax was zero until 1913.

The site rated his statement half-true.

In August of 2015, Democratic Presidential candidate Jim Webb also stated there was no federal income tax until 1913.

Politifact declared his statement as mostly true.

Until Congress ratified the 16th Amendment, there was no federal income tax. Congress did levy an income tax during the Civil War, but they allowed it to expire after the conflict ended.

Politifact used this as the basis to say Congressman Paul’s statement was half-true, but that Jim Webb’s claim was mostly true.

The site treats claims made by Democrats differently than Republicans.

Snopes is another site that is drifting into the territory of left-wing bias.

It used to be a clearing house for chasing down internet rumors.

But the site has recently added fact-checkers with a history of left-wing partisanship.

The Daily Caller reported:

“Recently, however, the site has tried to pose as a political fact-checker. But Snopes’ “fact-checking” looks more like playing defense for prominent Democrats like Hillary Clinton and it’s political “fact-checker” describes herself as a liberal and has called Republicans “regressive” and afraid of “female agency.”

Snopes’ main political fact-checker is a writer named Kim Lacapria. Before writing for Snopes, Lacapria wrote for Inquisitr, a blog that — oddly enough — is known for publishing fake quotes and even downright hoaxes as much as anything else.

While at Inquisitr, the future “fact-checker” consistently displayed clear partisanship.

She described herself as openly left-leaning” and a liberal. She trashed the Tea Party as teahadists.” She called Bill Clinton one of our greatest” presidents. She claimed that conservatives only criticized Lena Dunham’s comparison of voting to sex because they “fear female agency.”

She once wrote: “Like many GOP ideas about the poor, the panic about using food stamps for alcohol, pornography or guns seems to have been cut from whole cloth–or more likely, the ideas many have about the fantasy of poverty.” (A simple fact-check would show that food stamp fraud does occur and costs taxpayers tens of millions.)

Lacapria even accused the Bush administration of being “at least guilty of criminal negligience” in the September 11 attacks. (The future “fact-checker” offered no evidence to support her accusation.)”

In addition, Facebook has partnered with ABC News and The Washington Post to sort out what is and isn’t “fake” news.”

This gives conservatives concern.

That’s because warning labels aren’t the only steps Facebook is taking to stop “fake” news.

Stories labeled as “fake” will also appear lower in news feeds.

After the controversy where Facebook’s human curators excluded conservative sites from the trending news section, many on the right believe this fight against “fake” news is merely just a crusade by leftists to censor opposing views on social media.
