I don't buy the evil secret conspiracy theory. I mean there are evil secret conspiracies, but they're much more narrow, factional and ineffective than advertised.
Let's take Fake News. This is entirely a grass roots phenomenon. Sure there are individuals and groups behind a lot of it, but those individuals and groups are not heavily funded black ops teams of a billionaire conspiracy. They're sad white supremacist Reddit trolls. The fact that Trump blundered on to a wave of it and rode it to power is an accident, not the culmination of a choreographed master plan.
