Firstly, I don't think that anyone has suggested that loss of life in the miners strike - on either side - was justified.
Secondly, there are those who have decided a "cause" is worth dying for . . Unfortunately some of those are prepared to kill others at the same time . . .
Thirdly, why the separation between war and other "causes" - a distinction which is increasingly blurred, anyway . . Was the recent action in the Balkans a war? Strictly speaking, no.
Forthly, what "alternative viewpoint" are you looking for? Alternative to what?
