Is there a chance some of them are just ethically stalled at the age of three, unable to grasp the difference between truths and lies? “This is what I’d like the truth to be, so it is the truth.” I always figured that Trudeau’s biggest and most easily falsified whopper’s - e.g. “The story in the Globe is false!” - were because his egotism converted truths into mis/disinformation by whoever revealed them.

Edit: I guess that all fits in your psychologically impaired group.
