I don't 'make it out to be'. There are independent monitors. Figures ratified by UN.
There are human shields to be sure. You think these are willing human shields? All 12,000 dead are human shields? And you think that every house and hospital is a giant human shield justifying mass bombing and massacre and the destruction of basic supplies and essentials?
Your third question: because Hamas does not fight in the interest of the Palestinians. Hamas does not want a 2-state solution. Neither does Israel. So you have a battle of evil, a tragedy unfolding in which the real victims are not the Zionists or Hamas but the millions of stateless Palestinians who have been subjected to brutal occupation since 1948.
