It’s pure denial. I’ve met people like this.
They bought all the lies about Trump all the way along, because they couldn’t endure the truth.
Now they can’t tell you anything about his Presidency, because they SO saturated in their thinking with all the lies they don’t know anything true about it. They almost fully believe the lies are really what happened.
It’s a cult. If you ask people why they are members of the Trump Hate Cult, they will say “All my friends are in it”. They live in their echo chambers and hate everyone who isn’t in the cult.
They still believe Trump will destroy the world if he ever gets to be President.
