While every combatants have taken a side, not everyone taking a side is necessarily a combatant. I would say that of the examples you have given, some are definitely combatants, some may be combatants, and some are definitely not combatants. I do not view the concept of civilian / combatant as "anti-Israeli" since I do not believe a uniform is necessary in defining a combatant. Oh it, it makes identification easier, sure. The lack off makes it harder on the Israeli, sure. But it is not anti-Israeli.
Now let's be clear. I am sure that the rockets fired at Israel would also have caused significant civilian causalities if not for the Iron Dome. And even now citizens of Israel have to pay for the defence (I suspect it is more expensive to defend against the rocket then to make the rocket - or level Gaza). I am certainly not painting the Hamas as the good guys here.
But Israel is clearly the greater military power here. And with that power, I believe should comes responsibility. Civilian casualties may be a tragic consequence of any conflict (something unfortunate in itself), but that still doesn't mean it should be disregarded.
