We’re in a timeline now in which truth is entirely irrelevant.
Trump supporters are necessarily one of two things - deluded or dishonest. Either they’ve been manipulated into not seeing the plain fact that he’s a corrupt and self-serving autocrat and an existential threat to the US, or they know exactly what he is and just don’t admit it publicly.
In either case, truth and reality count for nothing.
In a sense, none of them know what they’re doing.
Many of them just don’t know at all. They’ve believed the lies and don’t realize that they’ve just elected a psychopath who is going to at the very least do considerable harm.
Some of them think they do know. They’re self-serving sacks of shit who look forward to tyranny and the destruction of democratic institutions because they think they’re going to benefit and they dont give a shit about all of the people who are going to suffer. But they don’t realize that in the end, they’re going to suffer too.
