Here is an extract from an article on reasons for wearing a white poppy :
"Many of us instead wear a white poppy, the symbol of peace. We do so not because we feel the suffering of those who died or were bereaved any less, everyone agrees that we should commemorate the sacrifice.
But we fear that in remembering the First World War, too many people in government and the military are using the compassion that people feel to justify present and future wars."
