CS Lewis said once, "“Suppose one reads a story of filthy atrocities in the paper. Then suppose that something turns up suggesting that the story might not be quite true, or not quite so bad as it was made out. Is one's first feeling, 'Thank God, even they aren't quite so bad as that,' or is it a feeling of disappointment, and even a determination to cling to the first story for the sheer pleasure of thinking your enemies are as bad as possible?"
A lot of Gaza discourse on this site feels to me like it runs off a determination to enjoy the sheer pleasure of thinking your enemies are as bad as possible. And there's plenty of grist for that - even if you don't invent any from whole cloth - but it's a destructive impulse and more than that it's a masturbatory impulse. It doesn't save a single person in Gaza. I don't know what will, but I think you have to start by doing your best to actually estimate the numbers you care about, not just pull out creative arguments for inflating them.
