To be fair, I don't think it's filled with fake news. It's filled completely with progressive-biased, one sided interpretation of actual news events.
/r/politics is how I imagine the "Two Minutes Hate" from 1984. A complete circle-jerk that has infested many of the main subreddits. /r/pics, /r/nextfuckinglevel, /r/publicfreakout are rather outposts of /r/politics these days. No wonder, when a small clique of politically aligned mods controls the major subreddits.
Even /r/askhistorians joined the blackout in support of 'Black Lives Matter'. What's neutral about that?
The emotional blackmail of this movement will probably be its undoing.
Go look at the official BLM list of goals - they are advocating to abolish the police, end capitalism, abolish the western nuclear family & several other far left, badly thought out, unsupportable concepts.
Worse still, the same campaign has spread to the UK, unfiltered and unchanged, despite the fact that we have almost zero people killed by police outside of terrorist attacks, our police don't carry guns, and due to our government's austerity policies, they're woefully underfunded.
