I've seen no mention of such on these boards, so why is this narrative being pushed?

Firstly it's to justify the 3rd world dictatorship optics that will surround Biden's inauguration*, surrounded by soldiers not people.

Secondly, when none of us show up, they will say "president trump has lost all his support."

Thirdly, they need a boogeyman. They know that if they don't keep the false dichotomy going the entire optical illusion they are carrying out will collapse. Once we refuse to engage and regroup in our heartlands, clearing house of RINOs and essentially leave them to it, the public are going to turn on them, and savagely.

We are their raison d'etre, unlike MAGA they have no positive platforn to present to the public, they are defined by what they oppose, as all the things that they propose are inherently divisive, inherently aimed at the minority.

In 4 years time they will not have a single supporter left, unless they can convince us to continue to be the bad guy, and present themselves as the lesser of 2 evils.

Without that false dichotomy, their evil is the only thing left on display.
