It’s not that their “fond” of it,
when your living in a delusion*, that is terrorizing you (Eg: the government is tracking me by my thought’s so they can come and kill me) you would do anything to prevent that, (ie wear tinfoil on your head so the satellites can’t find you)
If you knew without a doubt that someone is going to come kill you and you knew a way to prevent that wouldn’t you?
delusion implies an inability to distinguish between what is real and what only seems to be real, often as the result of a disordered state of mind.
**speaking from experience: no matter how strange, unbelievable, impossible a delusion may seem to you, when your living one, it is EXTREMELY REAL very possible, and terrifying, even if you knew 10 minutes ago that this isn’t real, it’s in my head, once it starts all of that goes out the window, and with some when it goes out the window it doesn’t come back, so for the rest of your life you are in that delusion…
or
they are fond of it because it’s shiny.
