It's like a dementia ward. The same pseudofacts, many from 2016, recited over and over by plaque-encrusted brains that can't absorb new information.
Forget trying to correct them. Focus on getting Gen Z and Y, the newest batch of voters, to the polls in twelve months. There is a planet to save, and democracy to resuscitate. Carry chocolates in your pocket, they always come in handy.
