Consider that the US and Israeli Governments are responsible for far more loss of innocent lives per year than any of these terrorist groups. Except here it's framed in the fight against evil, protect the people, spread democracy form which I guess makes it okay?
When it comes down to it if we accept that our platforms for discussion of the world around us are to be limited to the good forms (someone will decide for you which forms are good) than the terrible world has already won, and to me personally it makes no difference whether the innocent are dying by military sanction of some general's order or due to the influence of some crazy preacher.
