They literally believe that Democrats worship Satan, want to murder babies, are conspiring to destroy Christianity, want to turn all children into trans Marxists, and and so on and so on. If you believe your enemies are literally evil then you have a lot less problem justifying anything that subverts them. Even the ones who don't believe in Satan believe that the goal of Democrats is to enforce Stalinist Communism on them. It is a belief system totally disconnected from reality.

If you want to see how they see things, watch some Fox News, and you'll dip into their upside-down world. They just do not live in the same world as the rest of us, and have achieved total "epistemic closure." Of course, they would see the Democrat view of them — proto-or-outright fascist extremists hell-bent on destroying democracy, duped into serving the interests of billionaires and corporations, almost hopelessly misled by both domestic and foreign extremists — as being equally invalid (despite it being pretty easy to document, but part of that "closure" is that they reject serious evidence, and embrace the "throw everything at the wall" style of conspiracy theorists).
