What causes are worth sacrificing your children over?
Hamas wants to destroy Israel and is willing to sacrifice Palestinian childrens in order to achieve their stated goal. Apparently land is worth more than the lives of Palestinian children.
Hamas knows that if it launches enough rockets at Israel, eventually Israel will retaliate and innocent Palestinian children will die. The fact that Hamas continues firing rockets at Israel is an indication that it is willing to sacrifice Palestinian children in order to reach their stated goal.
Some children are a-holes.
Anyway, I guess the greater good of more children.
But most parents would selfishly, though understandably, still not sacrifice their own children.
No, the only thing in history parents have ever been willing to sacrifice their children for, are imaginary all powerful things in the sky called gods.
