I think that what people's parents did in the war shouldn't be held against them.
The Queen Mum was always praised because she stayed steadfastly in nearby Windsor when London was getting bombed, and made frequent forays out to meet the public.
Contrast that with my own dad, who scarpered over to France when war was declared, came back only briefly, then pissed off again to Africa, Italy and then Germany. The shame will always be with us.
