As someone with a family member who is falling into this non-sense, I will tell you it is extremely dangerous. We essentially have some teenager on 4chan trolling an entire audience of probably hundreds of thousands of individuals. They now believe Trump is our savior and the deep state wants to take him down. There are violent undertones to the entire conspiracy and I do worry they are going to turn into terrorists.
Anyways I thought it was kind of dumb and tolling, got a laugh and went on with my day. I think 2-3 days later I see QAnon being talked about on Fox News and CNN. My exact thought was "some guy in his basement must be thrilled that his shitpost on 4Chan landed on national TV".
It's crazy how people have fallen for it. Because if you read the actual conspiracy theory of QAnon it's batshit insane. The world order is being taken over by the Obama's and Democrats and the only guy that can save us is that dude that used to be on The Apprentice.
Like how do people not read that and think that the story is just too perfect to be true. Like seriously: Obamas are bad, Democrats and Hillary wants to take over the world. But WAIT WAIT!!! DONALD J TRUMP of all people is going to save you from the evil Democrats!
