The Last Jedi’s answer to the questions raised in The Force Awakens is...
...answers don’t matter.
There are no answers.
Everybody can fight with a lightsaber.
Everybody can use the force.
Everything communicated about the jedi in the original trilogy was meaningless.
The only meaningful thing is a stupid symbol.
Radical egalitarianism. Everyone is equally powerful if they just listen to their feelings.
That’s social justice.
That pretty much sums it up.
