First of all your use of biased language is ridiculous, you are as bad as the 'alt-right white-nationalish thug media' and I wish people like you had no place in rational discussions.

Second if you tell them to "Fuck off" you risk losing a significant chunk of your user base who believes their content and information is being manipulated against them. Facebook isn't in the politics business, they are in the social networking business. If Facebook is seen as political at all then a competing business will set up a service to sell to the other side. Look at what happened to mainstream media channels. Claims of liberal bias in the media giants directly led to the success of Fox News.
