@soatok It's not that surprising they love to view themselves as the "Goodguys". If forced to have to view it as a collection of choices instead of a default "Good" they are then forced to have to acknowledge all the racist, classist, etc shit they have backed and continue to back. It forces them to confront stuff they've backed instead of just blaming the "Badguys" of everything.
As such I would not say MAGA shatters their belief of being the "Goodguy", but re-enforces it. They say the "Badguys" are extra bad now. Sure, they are right that the Republicans are worse than they were, but it does nothing to change what they've done or are doing. Just makes it easier to asside by saying the "Badguys" are now extra bad. Especially since the stepping stones to everything that is going wrong now they had a hand in laying and this belief makes it easy to brush that asside as well.
