My answer to that is simply the lack of confidence and trust in the public. You're certainly going to have small proportions, as Professor Kitchen pointed out, of extremists who can be manipulated, but there's already fertile ground to be manipulated.
If you look at the overarching component of the public, who are more involved in this than I am, I think we can trust them. I think they understand when they are being taken down the garden path. Issues of the small minority becoming radicalized and violent probably existed prior to any misinformation or disinformation, whatever you define that to be. One person's disinformation is another person's truth. It's complicated.
I think we put too much of a scare sense, a panic, if you will, around this without stepping back and saying.... I'll put this bluntly: Trump won the 2016 election and it was not because of the Russians. That's an excuse that's then dragged out to explain this anomaly which the elites couldn't understand.
