I dabbled in it in the early 90's. Listened to Mark Scott on the radio every morning. The UN Black Helicopter stuff. Randy Weaver. Koresh. "New World Order". I think there were people always susceptiple to that way of thinking but with the rise of talk radio in the late 80's, along with usenet groups and message board (Pre Internet Days), it gave them ways to connect. They started to view George Bush as a 'globalist' and that's where you saw the early seeds of discord on the far right. The mixture of racism and populism which Perot tapped into. The internet itself didn't do much to to elevate it from where it was for 10+ years but social media did. And what did we have when social media took off? A black President. Perect combination and Trump saw that opening and capitalized on it.
