The same way any cult-like phenomenon divorces its followers from reality. In this case a charismatic demagogue (Donald Trump) has built a cult of personality around himself. He and his enablers employ many of the tactics used by other cult-like organizations, such religious organizations (e.g. scientology), or otherwise (i.e. multilevel marketing schemes). These organizations offer the opportunity to be apart of something "great" and "historic", to teach you how to be strong, to transform yourself from "zero to hero", and have fellowship with other like minded individuals who have the will and desire to improve their lives too. In return they demand absolute, unquestioning, and unwavering fealty. This has little to do with political orientation (left vs right) and everything to do with Donald Trump. There is currently a "civil war" going on inside the GOP, and the most vicious attacks from the cult-of-MAGA tend to be aimed at members of the political right who voice even the slightest dissent and are thus deemed "insufficiently loyal" (i.e. counterrevolutionaries).
