Their opinions on reality are not consistent. They will warp their minds into whatever twisted shape is required if they get to hurt the "other" (whoever that happens to be this cycle)
When it comes to their opinion of Hitler, their mind is shaped like an unbalanced dumbbell. He's a hero and a villain at the same time, but he's really only going to stay a villain to them for as long as it is necessary.
I'm constantly reminded of that 90s (I think) country song. "You've Got to Stand for Something or You'll Fall for Anything."
Many of them just keep falling for the next lie, even while the previous lies are being corrected. They never stop for a minute and think the place they are getting their info from is bad.
