I understand where you're coming from in the sense that the worldly awareness of children (and many adults) is inexorably stunted. But give them a
little bit of a break. Honestly, I wouldn't have been able to define those terms in much more detail until I was 20. If they want the knowledge,
they'll seek it themselves. If not I would think you should accept that as a choice of their own. If you want to guide them in that direction, help
by trying to pique their interest in such subjects. Crying isn't constructive
