Not giving a fuck isn't the same as apathy. Today I spent an hour waiting for some poor chap to repin a simple lock at the hardware store - I didn't give a fuck that he was a bit clueless and flying by the seat of his pants - but if someone scammed me tomorrow I would absolutely jump into action.

There are things that don't matter (someone a bit clueless working earnestly) and things that do (scammers, violence, etc). The goal is to differentiate and respond appropriately.
