There are many different things you can take or ways to read into this ban, beyond simply breaking rules and being banned.
An extraordinary event in Washington and you can choose to look at it in isolation.
In that case, Trump lost an election, doesn't fully accept it, refuses to go quietly and encourages base to act.
Base do what they did and it provided images that you'd usually see in Central Africa. It shocked the USA and the world.
You can also look at why things have reached this point.
Why Trump's base are politically active to the point of being up for what they did.
To cut to the chase
They really want what they were promised 4 years ago (Drain the Swamp)
Democray isn't working for them and doesn't represent them as per what it says on tin.
They still believe in Trump and can't see that he had no intention of draining swamp.
They prefer to believe that he wasn't allowed to, but here is the thing, in the case that he does try they'd be right. However he had no real intention to do so. Like Obama with Change, it was an election slogan, no more.
US Democracy is broken because the two parties are in bed with broadly the same interests who have bought and paid for it.
The general narrative that will be peddled is from a simplistic view formed from the isolated event and not the deeper more fundamental reasons.
Locking up the rioters of last week won't solve things, nor will time, as Trump leaves Office. The underlying issues will return and I think the real economic hardship coming down the road is what will trigger them. As Forlan said, the fire has been lit and is still burning. I'dd add, the sparks had been increasing for many years now.
That doesn't mean they will be able to revolt successfully. It is far more likely that a militaristic and dystopian reallity will dominate. The infrastructure for such counter measures is increasing. After the Great Depression in the 30's, very generally, the elites had to give back to the masses. Now, the elites feel as though technology and various circumstances allow them to keep taking.
US Democracy in it's current corrupted state is under attack and the people on both sides of political divides have good reason to be unhappy with it.
If they could see the bigger picture and if not come together, at least direct their cumulative protests towards the only place that will significantly change their lot.
For the Left, forget political correctness and look at the political system.
For the Right, forget Trumptown like politics and look at the political system.
