GP,
Let me try to explain it this way:
To answer your question: I have never hurt you, nor have the members here on the BB and I assume many many others in your life; a baby has never hurt you. The differences?????

Like I said, a baby is innocent & pure and the others can think and reason and are capable of causing pain. It IS this "lovableness, pureness & innoncence of a baby that makes the difference.
You say you never accuse a baby of inflicting pain, yet use the term "KILLED his mother during labor", implying that a baby is a murderer! You don't really mean it that way do you??
