If you come upon some people raping some kid in an alley that doesn't mean it's somehow okay for you stand there and just watch because "this is rape and quite frankly worse things were done in other rapes".
The argument "other people could have chosen to help and didn't, therefore it's fine for me to not help either" doesn't cut it.
All right, then take a plane to Egypt and start to personally deliver that aid, if you just can’t stand by as the moral and ethical pure person you are. No? Took your mouth too full? Maybe you are a Keyboard Warrior after all?
If you, personally, think it's morally fine to starve civilians and children that's one thing - luckily many disagree which is why it's deemed a war crime.
It is a war crime if it is actually done to starve the civilians, yes. And you love to throw around accusations, don’t you?
Why aren’t you fighting that the women and young children can flee - to Egypt or maybe even into Israel? That would actually be useful, don’t you think?
