No one is ASKING Jews to "prioritize Palestinian Children OVER Jewish Children". All that's being asked, of anybody, is that we all agree whoever we are, that it is just as indefensible to kill Palestinian children as it is to kill Jewish children.
There is no chance that anything positive can ever come of the killing of children from either Palestine or Israel.
It's equally wrong to kill children from either national community. Is that really such an unreasonable to thing to say?
Killing Palestinian children never protects or defends Jewish children.
