Yes, they are protesting a war that Hamas started on Oct 7, a war the Hamas could end at any time by laying down their arms and releasing the hostages. A war that started with a genocidal attack on Israeli men, women, children, and babies. It started by rounding up hundreds of hostages of all ages. It started by violating every known UN Rules of War and Geneva Conventions. Hamas, just lay down your arms and it will all stop.
