Facebook is well known to unfriend people and views that run counter to established (read conformist) climate views.

They have been sued by John Stossel for defamation on two youtube videos he posted.

Facebook got Climate Feedback to 'fact check'. They said the views expressed were false.

In court documents they claim that the views of Climate Feedback are mere statements of  opinion rather than factual assertions.

So according to Facebook it is ok censoring different thoughts; they are verboten. ::)
