Hamas murdered 20 Palestinian war activists in cold blood and just as many supposed collaborators, often chopping their heads off and then dragging them around the city tied to motorcycles. An effective tool for instilling fear.
But no one cares about these poor people. Not unless you can blame Israel. Then, and only then, is it news.
Thousands of Palestinians have died in a real genocide in Yarmouk—but the world only cares about Arab deaths if they can somehow blame Israel. In fact, Arabs only care about Arab deaths, if it can be a tool against Israel. They will even sacrifice their women and children in exchange for propaganda against Israel.
