@blatham,
Of course. It is an emotional response.
So now put your emotions to the side and tell me whose life is more valuable: a random child's or a random adult's? And why please.
Clearly, Barrack Obama is no hero of mine but he is to millions who would love to see him still in the White House. If you were someone who thought he was crucial to the nation's health and prosperity (and it would be dishonest of you to suggest there weren't a
great many people who believed such a thing) how would you measure the value of his life against a random teenager's?
People make these judgments. They may not voice them, but they make them nevertheless.
Going on about how the lives of children are more important than the lives of adults is, emotionally gratifying, and perhaps, in some cases, quite legitimate, but using such an emotional expression in an important discussion that requires clear heads, is cheap.
