Where are the liberal versions of boards where everyone is anonymous and venting their true feelings they deny elsewhere? ?

I'd be more inclined to believe that liberals are secretly plotting to overthrow capitalism and take away all guns if there were tons of popular anonymous boards circlejerking about it, the same way you see tons of white supremacy boards the moment you exit off the main highways of the internet. 

As it stands, it comes off more like people who do have extreme beliefs trying to project it onto the people who evidently don't.
