People get into these thigs for all kinds of reasons. My father fought in Spain as a volunteer - but he was on the other side.

To him the Republicans in Spain were the people who were burning churches and killing nuns, sort of Black and Tans, the sort he'd seen in action in Ireland. He found himself on the other side to people he'd fought alongside in the Civil War in Ireland - and on the other side to where I'd place myself for that matter.

And after Spain was over, he came back, and joined the British Army and fought against the Germans for six years all through North Africa and Italy.

When people do what they think is right it can get them into some strange places. And there's some good advice in the New Testament about throwing stones.
