Even if by some crazy implausibility it was the "greatest threat to our democracy since the Civil War", that's like saying, "Man, I just got a paper cut and that is sure the worst injury I've had since that accident where I was paralyzed from the waist down"
And are you kidding me? What if the mob had caught AOC or Pelosi? That would have turned from a "paper cut" to a political murder during an insurrection.
To be fair, that's not who they were chanting about hanging on the gallows they built. And, frankly, changing the outcome the way they wanted made uncooperative Republican targets more valuable.
