Listen, I don't agree with the "words will never hurt me" thing but trying to argue that by denying the utility difference of a broken arm is a lost cause for them.
Someone who's decided that the mental and physical pains and debilitations are wholly separate, especially here, will probably want cited studies and actual scientific evidence that the psychological community no longer believes that. Until that is presented no amount of semantics is gonna work.
Well i suppose that really depends on their mental fortitude, how much they let it affect them.
