One of Roddenberry's ideas that bugs me is the attitude to death in TNG. In 'The Bonding' we see that children are expected to repress their own feelings concerning the death of someone close to them and mourning someone is considered 'backward'.
It was in the episode Neutral Zone that Crusher (iirc) said something to the effect of "people in the 20th century feared death."
She said it in a way as to suggest that people in the 24th century naturally didn't.
Thing there is we've seen people struggle to save the live's of others, rush friends to sickbay, and even duck behind rocks when fired upon. Are these the actions of individuals in a society that possessed no fear of death?
