This explains it to me, but is why I disagree with the insurrection label. If armed people really wanted to "kill/hang" politicians and marched into the capitol with the intent to overthrow the government, I (and imo most people) would assume they'd use their weapons/be way more aggressive. You don't go for an insurrection, weapon in hand, and the worse that can be seen is someone having a selfie in Kamala's (?) office/people getting stomped. IMO if you can argue whether someone died from that protest, then it wasn't an insurrection, or else there would be no doubt about it.
Tldr; as far as I've seen there was not enough violence to show that they were going for an insurrection. At most it's a protest that escalated (as a lot of protests do, see BLM), which doesn't warrant the outrage it's getting.
