You can always distinguish the Jew-haters from those that actually care about Gazans by the manner in which they point out the poor situation of Gazans:

Folks who actually care will focus on the harms and NOT simply blame Israel, as it is Hamas and the Islamic Republic of Iran who are primarily culpable. 

The Jew-haters use Gazan pain as a hammer to excuse Islamofascism and demonize Jews.
