InfoWars is behind President Trump’s idea that the media is covering up terrorist attacks

Here is one answer from the press. I remember a lot of these instances.

And this is how propaganda is done. Ironically enough the more outrageous the lie, the more likely it is to work. I'm deeply saddened that many here are not only falling for it, but propagating the mis-information from sites like Infowars. I'm starting to fear this is the most insidious threat we face because we can't even begin to discuss solutions to problems if we can't agree on even the basic facts of reality.

This is happening for all the normal historical reasons. People who lust for power, privilege and money are playing on our basest fears and prejudices and damn the consequences. The people who are being suckered in will have trouble accepting this is happening for the same reason anyone who is conned has a tough time coming to grips with it. It's deeply embarrassing to admit someone has been conning you.

It's been known for a while that Trump, Flynn, and several others in this administration (and in Congress) have used InfoWars (and Breitbart, and Daily Caller) as a trusted news source, which is highly disturbing, as nobody in positions of power should ever be listening to such blatant propaganda and conspiracy-mongering factories. Note, also, that heavy reliance on these bullshit sites is entirely lopsided by party.
