Your simplistic thinking is what we consider unreal. There are a whole bunch of issues to consider here.
1. Isreal declared war on Palestine, therefore none of these attacks are terrorist attacks any more, they are simply freedom fighters fighting a war the best way they know how.
2. We have been given no proof that these "terrorists" the Israelis are killing are indeed terrorists, we have only the Isrealis word on that and we all know their history of dishonesty. In fact, those 6 year old kids being killed in marketplaces and so forth appear to be terrorists of the worst kind aren't they? Remember, it was Isreal who put a ban on the media, not Palestine.
3. Seems to me that it's OK by you guys to have "collateral damage" when it's in Palestine, but not so when it happens in Israel.
So yeah, I think blowing up civlians in a Pizza Parlour is terror, but then so is killing children who are shopping with their parents in a Palestinian marketplace. You see the first as worse than the second, but only because it was in Israel, I find the second far worse than the first because it is done with government backing by soldiers!. You appear not to care about the dead innocent Palestinians, lumping them into the category of "terrorist".
So yes, I'll stick with the term "so called terrorists".
