factidence
Factidence is when you act like facts are your personal bodyguards, and you won't let anything else touch you, even if it's a tornado of nonsense.
'I believe the sky is blue. I'm not going to listen to your nonsense about it being purple.'
'Even when my whole life is a mess, I still trust this fact like it's my best friend.'
'I'd fight a dragon for this fact. No dragon is going to make me doubt it.'
