The usual types of brainwashing can result in Stockholm Syndrome, but I think at bottom there is always a core resistance that eventually erodes the conditioning. I woke up thinking it isn't just them who have seemingly lost the ability to try out other realities and change their minds. Look at this forum any day and count the times that something is explained with "So-and-so isn't really who you think--not a woman, but a man [For some reason it is never 'that is a woman posing as a man'] -- not that person we knew but a body double -- not a double but wearing a hyper-realistic mask -- they are all really dead." The logistics of replacing the Pope, the Queen, the Clintons, Joe but not Jill Biden, the Obamas, the Pences, etc. with believable doubles that stay believable for months on end just don't pose a problem at all, and people who want to argue in favor of this great replacement are just as hostile to alternative explanations as the Branch Covidians.
