Here's the thing: trump isn't being a qanon threat. He's trying to act like a mob boss, and the qanon folks are taking advantage of the fact that by default trump quietly threatens people and organizations because of how he does business.
As for qanon itself: yeah, they are a threat, even if not an actual physical threat. I mean: some of them ARE a physical threat (like the nutter in the clown wig hunting democrats, or all that pizzagate bullshit.), but the sheer reach of their disinformation and the insidious nature they spread it, that's the actual qanon threat.
plus, you know, the assault rifles.
Pizzagate predates QAnon. If anything, QAnon is the evolved version of Pizzagate.
