No, this happens at the state level from time to time. There were protesters who broke in to state chambers to disrupt a vote on abortion rights iirc. There's also been the same on gun rights votes too. I can't find a link because any search for "protest" turns up yesterday's events.

Everyone wants to use words like coup or insurrection as outrage bait and more clicks and views. It denigrates the plight of people who have actually lived through the real version of those events. As a US citizen, it's embarrassing actually.

I’m not sure why you are not able to understand this. Disrupting legislation is not the same as disrupting the machinery by which we hand power from one executive to the next. Google “self-coup” or “autogolpe” to see how this is not exactly an uncommon action by would-be tyrants.

Do you have evidence that was their intent? And how exactly could they have succeeded, and kept Trump in power?

By their own admission, their intent was "revolution". It's really bizarre to me that you are continuously trying to whitewash these seditious traitors' actions in this thread. Is it a willful act of naivete, or something more disingenuous?

I am asking for rational explanations and evidence for the original claim that this was an attempted coup (something I have experience with sadly). Evidence and logic are valued here. You are accusing me of whitewashing sedition (I am not), being naive (I am certainly not on this topic), and being disingenuous (ditto) for taking that approach. I think you should re-read the HN guidelines.
