As a thought experiment, let’s say the American Revolution failed and the colonies remained under British rule. Do you suppose John Adams would have been able to hold any office of public trust in the British government?
I’m not saying what happened on January 6th, 2021 was or was not an insurrection or whether President Trump did or did not incite an insurrection. From a practical standpoint, however,I think it’s safe to say that successful insurrections work out better for the insurrectionists than unsuccessful insurrections.
If the start of the Revolution had failed, the insurrectionists would have likely been arrested and tried for treason -- probably ending in execution. They would not have held any office after that.

The other side of the scenario would be they avoided arrest and continued to rebel for who knows how long. The Revolutionary War lasted almost 8 1/2 years. As long as there are people who believe in a cause, there's no limit as to how long hostilities and other forms of disobedience could last. Look at the Irish and how long they fought for their freedom from GB.
Regardless, for anyone to says what Trump did has never been done in the history of the US downplays the even more extreme actions of those who rebelled against the crown and the local crown-placed governors.
The War didn't start because a few people sitting in a bar decided to break from England or because they thought an election was stolen. it was a series of escalations, including economic blockades and the attempt to seize the Concord Armory (gun confiscation to prevent armed rebellion). GB pushed the colonies into a corner, where the only solution was to break away from their colonial rulers.
The details are important, but they don't change the fact that our nation was born from rebellion and insurrection. if Trump is accused of the same, then he's in good company.
