It’s not complex at all. Palestinians have been ejected from their homes time and again by the State of Israel. Now they’ve been forced out of the West Bank and are all in Gaza, an open air prison. Hamas, a terrorist group, attacks Israel. Israel indiscriminately starts bombing Gaza where half of the inmates are children. Predictably, loads of civilians and children die.
People with a soul are on the side of the innocent civilians being murdered in an open air prison they were forced into by the apartheid Israeli government. It’s really that simple.
