You understand that you just said "they're the monsters for using human shields, but not us for shooting through the human shields", right?
Make no mistake, its 100% a war crime to use civilians as human shields. But that doesn't magically absolve the IDF of also committing a war crime. And if they can't meet their military objectives without committing war crimes, maybe that's a sign. In any case, bombing a hospital to kill a terrorist is a very efficient tactic if your goal is to create more terrorists. If you learn nothing else from the UK's administration of Mandatory Palestine, learn that.
Not a lawyer, but my understanding is civilian casualties are not unlawful (according to international law) when the target is legitimate (on the theory that it is otherwise impossible to legally fight a war with an enemy that hides behind its citizens). To be clear this is not to say war crimes are not also happening.
This is a business. They invented the game. They host it. How are they rotten for wanting to make money from it?
These aren't real objects. They are entry in a Valve database. I can't understand why people get emotionally, much less financially, invested in it.
