They took the tactic from modern day Christian televangelism.
They use Trump as the focus of a belief system
They twist the old and outdated morality of hyper patriotism and conservative values. They do this in order to cherry-pick rules and laws to form a grotesque dogma that bares little resemblance to the original intention of said laws and morality.
They then use the twisted dogma to manipulate the population. They do this by feeding into the fears of poverty, 'evil', xenophobia, and racism. Then they offer solutions to those issues so long as they tithe (donate money), worship, and "spread the good news."
The solutions offered are wildly unrealistic… Free money for loyalty? Killing a whole group of people?
Unless your name is Israel, those solutions are obviously a farce to anyone with even the smallest amount of situational awareness and common sense.
That's why a lot of the Trump propaganda dulls the common sense and attempts to rewrite the memory of others using memes and obvious lies.
You have to essentially hypnotize people into believing that they are being oppressed, attacked, and that everyone but those a part of the belief system are evil baby-eaters.
One of the major reasons that fundamental Christians and the tea party generation are such numerous Trumpism supporters…
The hard work of brainwashing them was already done by another religion. All the MAGA leaders had to do was swap out one god for another.
It worked for ancient Rome, and it's working here.
