It's not just the raw suffering but also the sense of systematic oppression between groups that triggers people. Yemen or Sudan don't get nearly enough attention because most people find those conflicts harder to understand in terms of "good and evil" than the Israel-Palestine conflict.

We are bombarded by the suffering because it suits the left self hate narrative and Hamas operatives are always on hand with expensive photography equipment. Palestinian suffering is literally part of their strategy to turn the kids in America against Israel. It's a dumb strategy, but Palestinian society has chosen dumb strategies for nearly a hundred years now. Antizionists will sacrifice an infinite number of Palestinians to its hateful fantasy of destroying Israel.
