Of course it was violent, all riots are violent by definition. It is absurd hyperbole to call this an insurrection just like it would have been absurd to call the far more violent riots during the Trump inauguration an insurrection.
I was personally at trump’s inauguration filming the protests and I can assure you they were not nearly as destructive as the January 6th insurrectionists trying to overturn an election. A few smashed windows and some flipped over trashcans is not a mob attacking the capitol chanting “HANG MIKE PENCE.”
